Now find the measure of ∠YOZ. Which angle relationship did you use?

m∠YOZ = 60°

Step-by-step explanation:

Because it's given that m∠VOX = 90° and m∠WOX = 30°, we can find that m∠VOW = 60°.

Using the Vertical Angles Congruence Theorem, we can identify m∠YOZ = 60° because VY and WX are intersected, meaning their vertical angles are congruent.
