Answer:
Measure of ∠WOV = 60°
Complementary angles
Explanation:
The box shows us that is equal to 90°. Angles ∠WOV and ∠WOX are complementary angles because we get 90° when we add them together. Since we are given the measure of ∠WOX we can subtract it from 90° to find the measure of ∠WOV.
90° - 30 ° = 60°
