Yes I originally thought 90 but then noticed the absence of a right angle sign. Also 60+40=100 which means the last angle should be 80. Making that perpendicular 100/80
You start from left, and calculate them 1 by 1, based on the angles that you already know. It is quite simple actually, you just have to know they always add up to 180 (within triangle, and when you “split” the space over a straight line).
135° for anyone wondering.
correct, just commenting the 100/80 intersection looks like 90/90, i think it was intentionally misleading, classic trying to get you problem

I’d get out my red pen and write: “Bad diagram. -1pt See me after class.”
Yes, simple doodle below for anyone wondering.

you mean to say the right angles aren’t right angles? disgusting, get this outta my sight
evil math teacher laughing in background
this diagram does not provide a right angle indicator, and thus should not be assumed as a right angle
yes that’s the stupid excuse my math teacher would give
For context: it used to be 675° a few years back so the math checks out.
that’s not how global warming works
I got 125.
180-(90-35)=x 180-55=x 125=x
It isn’t 90 degrees because the image is misleading. 60+40+y=180. y=80
