Question

He angle measurements in the diagram are represented by the following expressions.

\qquad \blueD{\angle A= 5x - 5^\circ}∠A=5x−5
∘
start color #11accd, angle, A, equals, 5, x, minus, 5, degrees, end color #11accd \qquad \greenD{\angle B= 3x + 13^\circ}∠B=3x+13
∘

Answer 1

It was 48

Did it on khan hope this helps :)

Answer 2

<B = 40degrees

x = 9

Explanation:

Find the diagram attached. From the diagram, <A = <B (corresponding angle)

5x - 5 = 3x+ 13

5x - 3x = 13 + 5

2x = 18

x = 18/2

x = 9

Since <B = 3x+13

<B = 3(9) + 13

<B = 27 + 13

<B = 40degrees
