135 is correct. Bottom intersection is 80/100, 180-35-100 = 45 for the top of the second triangle. 180 - 45 = 135
Mathematician here; I second this as a valid answer. (It's what I got as well.)
Random guy who didn't sleep in middle school here: I also got the same answer.
Random woman who didn't sleep very well last night. I got a different answer, then thought about it for 10 more seconds and then got 135.
(No I didn't assume the right angle, my mistake was even dumber. I need a nap.)
