you can figure out that angle 5 equals 81 because 52 + 47 + 81 = 180, angle 4 = angle 5 (81) + 52 so angle 4 is 133 angle 1 is angle 5 (81) + 47 so angle 1 is 128. Knowing these angle 2 would be 52 and angle 3 would be 47
for simple answers
angle 1 = 128
angle 2 = 52
angle 3 = 47
angle 4 = 133
angle 5 = 81
