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.
To be fair I wrote the answer, then figured “surely somebody else must’ve written an answer by now”, refreshed, saw two other answers (one 12 seconds old), thought “fuck it” and posted anyway. They’re all written a bit differently so maybe some are easier to understand than others.
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
