Select the correct answer form each drop-down menu. Glven: m XWOZ = 90°
Prove: m XWOX =

Y
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°

Consider the following equation -167 + 37 = 49 - 21p select the equation that has the same solution as the given equation. o a. p - 5 + ip = 7 - p ob. +55 + 12p = 5p + 16 c. 2 + 1.25p = -3.75p + 10 d. -14 + 6p = -9 - 6p reset next
