Question

Find the measure of ∠ J. (Hint: You must find the value of x first)

Answer 1

35°

Explanation:

set it equal to 180 because the total sum of the interior angles of a triangle is equal to 180

x+x-15+95=180

2x+80=180

2x=100

x=50

now plug it in

50 - 15 = 35

Answer 2

35°

x+x-15+95=180

2x+80=180
