PLEASE HELP ASAP If mZYWZ - 17, what is mw
?
34
73
56
17

Answer 1

73°

Explanation:

Since WX = WZ then ΔWXZ is isosceles and WY is perpendicular to XZ

Hence ∠XYW = 90°

YW bisects XWZ, hence ⇒ ∠ YWX = ∠YWZ = 17°

The sum of the 3 angles in ΔWXY = 180°, hence

∠WXY = 180° - (90 + 17)° = 180° - 107° = 73°
