∠A=5x−15

∘

start color #11accd, angle, A, end color #11accd, equals, start color #11accd, 5, x, minus, 15, degrees, end color #11accd \qquad \green{\angle B} = \green{2x +21^\circ}∠B=2x+21

∘

Here we have two congruent angles ∠A and ∠B. Remember that angles are congruent if they have the same measure, so:

Substituting x in one angle:
