The angle measurements in the diagram are represented by the following expressions. \qquad \blueD{\angle A=5x -12^\circ}∠A=5x−12 ∘ start color #11accd, angle, A, equals, 5, x, minus, 12, degrees, end color #11accd \qquad \green{\angle B=2x + 24^\circ}∠B=2x+24 ∘ start color #28ae7b, angle, B, equals, 2, x, plus, 24, degrees, end color #28ae7b The answer is 48 :)
