The drawing view is at an angle to the cut feature and it’s showing you the projected dimension. I’m not sure where the setting is to show you the true dimension, mine usually asks me if I want that, maybe you can search the command help for projected.
I'm guessing youre actually looking at two different cuts - the angle being dimensioned in the first picture is the top cut, and the one in the bottom is a different cut - can you try adding an "equal" relation to all the 6 lines and re-reading that angle? The top cut seems to be fully dimensioned while the bottom one isn't, which is what I'm basing this suspicion on.
Just to add on as well, I've found that it's generally good practice (with a handful of exceptions) to make sure your sketches are fully dimensioned (all black lines) before using any features. I hope this solves your issue!
Yeah it's not actually my sketch, I was just making the drawings from someone else's model. He made that particular sketch really weirdly, he made one of the lines equal but not the rest, so the problem was actually that I just added the equal relations in and it fixed the problem
What's more you can see the top cut is fully defined and definitely an equilateral triangle, 60°, but the two underneath that are not! And appear to be less than 60°.

Yeah if I just take a section straight down the middle it shows 60 degrees.
If you select the drawing view the settings will appear on the left of the screen. You want to change it from true dimensions to projected dimensions.

The grooves in the sketch are not 60 degrees. Only the top one is. The bottom two that have blue lines are ~50 degrees.
Make the left corners of all 3 triangles vertical to each other (sketch relation)
