The answer is 125 degrees but the triangle on the left has 190 degrees in it

Either this is drawn wrong or they broke geometry

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

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

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

[-] Skasi@lemmy.world 8 points 1 week ago

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°.

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

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

[-] De_Narm@lemmy.world 6 points 1 week ago

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.

Am I stupid or is one triangle unnecessary?
