Answer:
Answers in explanation.
Step-by-step explanation:
Finding angle 1:
52 + angle 1 = 180
angle 1 = 128
Finding angle 2:
128 (angle 1) + angle 2 = 180
angle 2 = 52
Finding angle 5:
52 + 47 + angle 5 = 180
angle 5 = 81
Finding angle 3:
angle 2 + angle 3 + angle 5 = 180
52 + angle 3 + 81 = 180
angle 3 = 47
Finding angle 4:
angle 3 + angle 4 = 180 OR angle 4 + 47 = 180
47 + angle 4 = 180
angle 4 = 133
