Answer:
68°
Explanation:
Attached is an image of the isosceles triangle theorem.
Utilizing this theorem, we know that the bottom two angles are congruent, or the same.
We also know that there are 180° in a triangle. Lets find x!
1) Write an equation to find angle x:
56+56+x=180
2) Simplify
112+x=180
3) Subtract 112 from both sides:
x=68°
