Angles of a triangle always add up to 180. So what must the third angle be to get up to 180?
OpenStudy (anonymous):
62?
OpenStudy (anonymous):
Yes. Nice.

thankkks
OpenStudy (phi):
you can check by adding up 62+18+100. If 62 is correct, you will get 180 the fast way to find the answer is 180- (18+100)
