Complete the proof.
Suppose WOX # 90°
By the
XWOX is supplementary to XWOZ. Therefore,
mwox + m XWOZ = 180°. By the assumption and the substitution property of equality, 90° + m *WOZ # 180°
Using
the subtraction property of equality, the measure of angle WOZ
90°, which contradicts the given. Therefore, the
assumption is not true, and m WOX = 90°
