Question

How do you solve this problem? (see picture) *I kind of just guessed but I need to know how to solve*

Answer 1

All of a triangles angles added up make 180. when theres a 90, its a lot easier, all you have to do is take 180-90 which is 90 and divide 90 by 2 because there are two unknown angles which is 45 and angle A is slightly bigger than angle B (we'll say about 5 degrees bigger) so the answer would be 3) 50

Answer 2

The answer would be 50........
