Answer:
<h2>x = 36°</h2>
Step-by-step explanation:
We know: the sum of the angles in any quadrilateral is 360°.
Therefore we have the equation:
108 + 108 + 2x + 2x = 360 <em>cobine like terms</em>
(108 + 108) + (2x + 2x) = 360
216 + 4x = 360 <em>subtract 216 from both sides</em>
4x = 144 <em>divide both sides by 4</em>
x = 36
