Question

49)
w z
120°
x y
?
ss angles are supplem

Explanation:

Step1: Recall parallelogram angle property

In a parallelogram, consecutive angles are supplementary (sum to \(180^\circ\)).

Step2: Apply the property to find angle \(Y\)

Angle \(Z = 120^\circ\), and angle \(Y\) is consecutive to angle \(Z\). So, \( \angle Y + \angle Z = 180^\circ \).
Substitute \( \angle Z = 120^\circ \): \( \angle Y = 180^\circ - 120^\circ = 60^\circ \).

Answer:

\(60^\circ\)
