Answer:
90°
Step-by-step explanation:
It looks slightly obvious, but here's the complicated explanation.
Converse of the Consecutive Interior Angles Theorem. Solve.
x+96+x+96=180
Simplify.
2x+192=180
Subtraction Property of Equality (subtract 192 from both sides to isolate 2x).
2x=-12
Division Property of Equality (divide both sides by 2 to isolate x).
x=-6
Now that you have your x value, plug it in into your bolded equation.
x+96
-6+96
Simplify.
90°
