Hey Guys!

I have a question here. I found the answer. All I did was find all the measures of the angles (Angle 3 = 68, Angle 2 = 68, Angle 1 = 44)

All add up to 180. I divided 44 / 2 = 22 and 68 / 2 = 34

34 + 22 = 56

180 - 56 = 124

Measure of Angle 5 = 124.

Can anybody tell me the reason why this is the correct answer? I did not know what I was exactly doing while trying to solve the problem. Well, my final answer was 56 but I did not know I was supposed to subtract it from 180. Can somebody give me a quick walkthrough on how to professionally solve this?
