Question

I can't figure out #13. Can someone help me?

Answer 1

Well I would have to say to do 180 - 28 which equals 155 then I would do for number 4 that is a 90° angle then minus that from 155 which equals 65 then for numbers 1 and 2 angle 2 equals 28° and then number 1 equals 155
hope this helps

Answer 2

angle 1-152
angle 2-28
angle 3-62
angle 4-90
