135° for anyone wondering.
Yes, simple doodle below for anyone wondering.
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).
you mean to say the right angles aren’t right angles? disgusting, get this outta my sight
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

correct, just commenting the 100/80 intersection looks like 90/90, i think it was intentionally misleading, classic trying to get you problem
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
What a bunch of bullshit. Just draw it way off 90 if you don’t want people to use a protractor. I calculated 125° because of this (but I’m happy I still got the right wrong answer, if that makes sense)
I got 125.
180-(90-35)=x 180-55=x 125=x
You’re assuming it is a right angle
Nothing states that it is
Even if it was a right angle, I think a second assumption is that the top left and bottom lines are equal length, which is also not stated.
I think there’s just not enough information in this picture to calculate the angle, and it can only be determined by measuring. But the image also does not specify that it is drawn to scale.
I hated pictures like this in school. The numbers are just slapped on an inaccurate image and somehow they expect people to ignore the obvious right triangles and just focus on the math part of it.
If it was to scale you could just use a protractor and skip the whole math part, which is the entire part of the lesson…
Then they could use decimals so it’s unlikely to get it right without calculating, 60.17°, 40.29°, 35.43°
