Question

M 2 = 40°, m 4 = 150°, m 3 =

Answer 1

Hello!

First you have to find angle 1

angle 1 and angle 4 are supplementary meaning they add to 180

angle 1 + angle 4 = 180

angle 1  + 150 = 180

angle 1 = 30

The angles in a triangle always add up to 180

angle 1 + angle 2 + angle 3 = 180

30 + 40 + angle 3 = 180

70 + angle 3 = 180

angle 3 = 110

The answer is 110°

Hope this helps!
