I like that all the comments are people discussing the diagram.

Right one does not depend on the left one. 3rd dimension for the win!

C'man there's totally a 1px shift on the line. You can't just assume it's a right angle.

125°

Edit: Damn I'm getting roasted for getting it wrong. I totally am wrong, but when I've been awake for only 5 minutes that's bound to happen XD

It's a trap. The drawing is misleading. If the left triangle already has 60° and 40° then only 80° remains. Meaning there's no right angle. The vertical line should be leaning to the left slightly. The correct answer is 135°.

Or 135°

[–] Quacksalber 7 points 1 week ago (1 children)

Wrong, as the drawing is not representative. The inner lower angle for the right triangle has to be 100°, as such the inner upper angle has to be 45° and the X angle has to be 135°.

Federation in action: 5 different people from 4 different instances correct OP, not knowing the others have done so, because federating the answers takes a minute.

Good on you for admitting fault, not deleting the post, and standing strong. I know you probably feel like a total braindead fucking moron right now - and you'd be right to - which may be the only thing you've gotten right in your whole life. /s

the answers here assume that the base is a continuous, straight line

given one of the angles on the left triangle is a right angle on the diagram, but 80 if you calculate it, you can't assume that

[–] [email protected] 11 points 1 week ago (3 children)

This is a standard way to draw geometric proofs, it's not at all unreasonable to assume straight lines and unrepresentative angles.

Doing 5th grade math makes me feel like a fucking genius. Cant believe I figured it out tbh

Seeing the other comments, it might be worth a shot to repost this meme with your math homework thrown in for easy solutions.

Of course, I did the math too before looking.
