Answer:
126
Step-by-step explanation:
angle ZWY = 180 - 90 - 63 = 27
Base on the given information, the length of XW is same with the length of ZW, which means they have the same angle.
Quadrangle has angle of 360
360(quadrangle) - 27(ZWY)- 27(XWY) - 90(WZY) - 90(WXY)
= 126
Class A: 3 out of 30 = 3 / 30 = 0.1 = 10%
Class B: 28 out of 40 = 28 /40 = 0.7 = 70%
Class C: 11 out of 28 = 11 / 28 = 0.39 = 39%
Class D: 14 out of 50 = 14 / 50 = 0.28 = 28%
The answer is Class D
