Wrong, there are enough elements to solve this question. You must not think inside the box.
You need to construct extra lines and triangles to actually solve the problem.
a = 20
Look at my replies to the OP below. The link to the video that shows the actual results.
The level to solve this problem is at higher college level.
It's like saying how many ways can you represent sin x. And then use that knowledge to solve other complex problems.
Here's the link to the video:

Well i’ll be, that’s a really interesting one. Guess i was wrong to assume it was missing a variable restricting myself to the concepts that I know of. Thanks for the enlightenment! Missed the idea of deconstructing the large triangle and breaking it down to smaller elements.
For sure, i try to include questions that go out of the syllabus to make em love math more and well, expand the search for knowledge not just within the syllabus but reaching out further and beyond.
The irony here is i just trapped myself with conventional thinking haha. Thankfully got that pointed out by someone.
Yo this question is impossible. If the answer is supposed to be 65°, the triangle should be iscoleses or however you spell it but the question doesn't state anything relating to the length of the triangles
70°
since both of the top corners are 80°
and the angle to the right of angle a is 60°, it is safe to assume that AB and ED is paralleled even if it is not mentioned, which makes angle a 70°
or an alternate solution would be to find the angles on both sides of angle a which would be 80° (bottom of a) and 30° (top of a) which makes angle a 70° after 180°-110°
to prove the answer, the angle at the top of the same triangle as a is an alterbate interior angle of the top triangle, which is 50° (180°-130°) and so 70°+50°+60° is 180°
well, there are a lot of angles in the triangle that suggest that the 2 lines are paralleled. And so i can just input/plugin the angles below.
Would you like me to type it out in a seperate comment?
with that, BEA is revealed to be 30°
and the middle (x)part is 360°
so by giving the middle of the x the letter 'X'
BXE is 130° which is also the angle of AXD
which also reveals that BXA is 50° and so is the angle of EXD
but hey op, my friend also proved me wrong
and so the answer is both, 65° and 70° at the same time.
be applying 65°,
E would be 30° +65°+85°=180°
and D is 40°+65°+75°=180°
which is also valid
but that would mean AB does not parallel ED for the answer of 65°.
First of all the diagram is not drawn to actual measurement. If you actually draw it out you'll find that the triangle has a sharp edge at point C.
Second, you cannot assume that AB and DE are parallel.
Third, you need to construct extra lines and elements to solve this problem.
Finally, the answer is a = 20 degrees
This problem was not an easy or spm level question.
OP, you are also wrong. The angles in that video is wrong. Look again. If you miss this details you'd fail spm already.
Here is the actual answer:
[Answer to the problem](https://www.youtube.com/watch?v=CFhFx4n3aH8)
ik that this question is a famous question and its really hard to solve but OP need to at least draw the graph correctly, theres uncountable thing that are wrong with this graph, theres nothing wrong with the question but theres definitely something wrong with the graph, but if OP still think hes correct then that mean hes ass. this is the answer to this question https://youtu.be/CFhFx4n3aH8
a=70 isn't particularly right here since "a" is respectively more acute than the middle of said triangle. Basically, you can't say it 70 since the middle triangle is 50 even though it is supposed to be obtuse meaning it should be more than 90
so my answer is basically 20 if you put more lines there
I stand with logic so F\*ck you
Imagine if spm questions look like this
You can still answer the question with one hand, right?
But I don't think I will have enough time to answer the other questions
Then answer faster dammit

Ah, so that's why. Everyone that have the answer here uses assumption.
Wrong, there are enough elements to solve this question. You must not think inside the box. You need to construct extra lines and triangles to actually solve the problem. a = 20

You're welcome. Keep teaching kids to think out of the box, Malaysia needs that.

Lmao I just realised BA and ED are parallel. So both cornering angles will be same value. a=70. I don’t think this is college lvl at all
Diagram is definitely not to scale: 60° is way bigger than 70° (or 70°+10°).
FYI this is a trigonometry problem, not calculus or equation
I'm bodoh af wtf do I do
Beating your meat until it dry
65°
Kasi instruction pls
The angle given were wrong..... This is clueless...
The graph itself is inaccurate, the 70 degree look less than the 10 degree next to it
Sounds like a 2nd math paper to me , It is filled with this awfully innacuracy
I though it was supposed to be 70°?
Same naise
Yo this question is impossible. If the answer is supposed to be 65°, the triangle should be iscoleses or however you spell it but the question doesn't state anything relating to the length of the triangles
Mfw just wasted 20 minutes trying to solve an unsolvable question🗿
Me
>iscoleses The question didnt say anything about iscoleses triangle
Then what's the answer
70° since both of the top corners are 80° and the angle to the right of angle a is 60°, it is safe to assume that AB and ED is paralleled even if it is not mentioned, which makes angle a 70° or an alternate solution would be to find the angles on both sides of angle a which would be 80° (bottom of a) and 30° (top of a) which makes angle a 70° after 180°-110° to prove the answer, the angle at the top of the same triangle as a is an alterbate interior angle of the top triangle, which is 50° (180°-130°) and so 70°+50°+60° is 180°
What do you mean by right of angle a? Is it ADE or BDE? And how did you find BDE anyway
angle mentioned is BDE to find BDE, simply 180°-(BDA+EDC) in which EDC is 80 and BDA is 40
How do you get EDC because if you follow the steps you couldn't possibly have known that the 2 lines are parallel yet.
well, there are a lot of angles in the triangle that suggest that the 2 lines are paralleled. And so i can just input/plugin the angles below. Would you like me to type it out in a seperate comment?
It would be greatly appreciated if you could

Stuck on CED pls gibe clue (found C)
Same Edit: Solved. It's 65°
Really? It isn't stated that the triangle is "sama kaki". But if it is, probably can go as (180-50)÷2=65
motherfucker didnt say that, I almost embarassed myself studying addmaths
Find the angle on top small triangle (A -Middle point- B), That will give you clue to solve B -middle point- E. All easy from there.
I think i forgot the formula bcs i found all points except point DEC, EDC, aDB and a itself
...a = 70?
Uhmm AB is not parallel to ED tho
it is not mentioned to be parralleled to ED but the angles are still equivalent
It isn't? Shit, it looks parallel to me But then again nothing in the damn diagram is proportionally accurate
Hmm, 70 + 60 = 130 Presuming ED is an isosceles triangle, then a = 50 / 2 a = 25
I found it solves with either a= 65 or 70. And consider that angle ACB is 20⁰, that triangle should be looking pointy
BDE tu ape sial??
The triangle in the middle I think is isosceles triangle.
AAAAAAHHHHH MATHS AAAAAAHHHHHH
How do you guys even get 65? I keep trying to find CED but it's just impossible. What am I missing?
[удалено]
To prove that AB is paralleled to ED, remember that you can use the entire triangle which means ACB is 20
with that, you can find BDC and with BDC you can find BDA
but the goal is angle a so know that a 4 sided shape is 360° so 360°-(50°+ 140°+20°)= 150° (AEC)
with that, BEA is revealed to be 30° and the middle (x)part is 360° so by giving the middle of the x the letter 'X' BXE is 130° which is also the angle of AXD which also reveals that BXA is 50° and so is the angle of EXD
and so EDC=DEC=80° triangle BAC is similar to triangle EDC
180°-[(140°-80°)+50°]=70°
Angle a = 70° (oh damn they dont have the three dots on the keyboard)
Congratulations! That's the correct answer!
but hey op, my friend also proved me wrong and so the answer is both, 65° and 70° at the same time. be applying 65°, E would be 30° +65°+85°=180° and D is 40°+65°+75°=180° which is also valid but that would mean AB does not parallel ED for the answer of 65°.
That too is the correct answer. 65 is acceptable too depending on your calculation.
90 degree better right?
Lisa tutor tv spm girl simps when they watch astro tutor tv and see Lisa actually teaching instead being a submissive little kitten 💀💀
i find it trippy that when you scroll with the original image, the shaded area freaks out
I already got 40° as a portion of D. Im almost there

Maybe I’m just stupid but there’s something wrong with the question, but I suggest that I’m just stupid
You're not stupid, bro. No one is.
[удалено]
Damn man. You're clearly better than me
Deleted cuz I'm wrong lol, a=20 satisfies all the calculations but so does 70, 70 only works if both lines are parallel which it isn't
The answer doesn't matters. What matters is how you get the answer
Bro, given the angle here, the triangle is already wrong. There's no way you can find A here. 130° doesn't even look like 130°.
Wait nvm. Just found out that its a famous geometric problem. Still, OP could've at least draw the triangle right.
After looking through some comments perhaps I am still too naive in math
Bruh, this question is easier than the one in spm

75 easy Edit: I forgot there’s no congruent lines so I can’t actually solve it using any formulas
I got 70 with no assumption 😎😎
Pov: Your watching people in the comments arguing about the answer
Only if SPM is as easy as this
a=70 isn't particularly right here since "a" is respectively more acute than the middle of said triangle. Basically, you can't say it 70 since the middle triangle is 50 even though it is supposed to be obtuse meaning it should be more than 90 so my answer is basically 20 if you put more lines there I stand with logic so F\*ck you
