Answer
X=96
Explanation
You have to add up the two interior angles, the angles inside the triangle, to equal the exterior angle.
If you want to check the answer put 96 back in the x's spots. The interior angles would equal 145 and the exterior angles would equal 145 as well.
X=96. This is because find all the interior angles and subtract, you will get 96 degrees.
