Answer
X=96
Step-by-step explanation
You have to add up the two interior angles, the angles inside the triangle, to equal the exterior angle.
- x-47+x=x+49 Combine like terms that would be the x's which would equal 2x
- 2x-47=x+49 Add 47 to both sides 49+47=96
- 2x=x+96 Subtract x on both sides 2x-x-x
- x=96
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.
