Question

Two intersecting lines create four angles; 22 and /4 are a vertical pair. Their sum of their measures is equal to
110°. What equation will solve for the value of each angle? (1 point)

Answer 1

Let x = measure of ∠2 = measure of ∠4 (vertical angles are congruent).
Then x + x = 110°, so 2x = 110°.
Solve: x = 55°.
