Question

∠A=5x+20

∘

start color #11accd, angle, A, end color #11accd, equals, start color #11accd, 5, x, plus, 20, degrees, end color #11accd \qquad \green{\angle B} = \green{9x -92^\circ}∠B=9x−92

∘

start color #28ae7b, angle, B, end color #28ae7b, equals, start color #28ae7b, 9, x, minus, 92, degrees, end color #28ae7b


Solve for x and then find the measure of \blueD{\angle A}∠Astart color #11accd, angle, A, end color #11accd:

Answer 1

angle a = 5x +20

5x= -20

x=-20÷5

x= -4
