Question

What is the measure of X , in degrees?

Answer 1

Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.

All inner angles must add to 180 degrees since it's a triangle.

70+70+x=180

140+x=180

x=40

Explanation:

Answer 2

71°

Explanation:

The angle of x and angle of 109, are supplementary, which means when added they are equal to 180 degrees.

109 + x = 180

x = 180 - 109

x = 71
