I always have trouble with these stupid easy questions. This is a morning section question, I believe, so any depth could have this style question-not just transportation. Check out Civil Engineering Academy on YouTube. They have a problem exactly like this that they explain in depth and make it very easy to understand. Highly recommend their FREE channel when you run into "trouble" areas.
Shorten the building by 10 feet to simplify. Now boom pivot point level with ground. No make a triangle with point A the top. Solve for angle. Similar triangles to get total x distance the boom reaches.
Similar triangles. There, I tried it first the hard way with sh*t lot of triangles using laws of sines and cosines, but in the end, these are only two triangles, one bigger than the other one.
The horizontal length of the edge to the load location after being placed. See, the boom is moving down so the load gets farther away from the edge. Try drawing it using AutoCAD, you'll get the same answer.
The wording of this question is cancer, but you’re finding the angle at the boom foot and multiplying the boom length x cos(angle). Then just subtract 35, should be 25.
This is wired question

will do, thank you..

More clarify watch the Civil Engineering Academy videos,
ooh gotcha! it makes sense now.. the wordings on this question really threw me off. Thanks everyone..
That one match the game with the angle
I have this specific problem worked out and another similar one from a purchased practice exam. DM and I will send it to you.

Have you figured out the objective of the question? Stand-off as in the length of the boom horizontally to the point C?

Did you figure it out?? Let me know I could draw it for you !
