Question

Find the measure of angle A

Answer 1

m(<A) = 117°

Explanation:

Sum of angles of triangle = 180°

So,

x + 5x -8 + x + 13 = 180

7x + 5 = 180

7x = 180 -5

7x = 175

x = 175 ÷ 7

x= 25°

So, m(< A) = 5x-8 = 5 (25) -8 = 117°

Hope that helps,

Have a nice day

Answer 2

x + 5x - 8 + x + 13 = 180

7x + 5 = 180

7x = 175

x = 25

Angle A measures 5(25) - 8 = 125 - 8 = 117°.
