Question

What is the measure of x?

Answer 1

x = 36°

Explanation:

We know: the sum of the angles in any quadrilateral is 360°.

Therefore we have the equation:

108 + 108 + 2x + 2x = 360 cobine like terms

(108 + 108) + (2x + 2x) = 360

216 + 4x = 360 subtract 216 from both sides

4x = 144 divide both sides by 4

x = 36
