Answer:
x = 68°
Explanation:
There is Two Option:
Option One: Looking at the side length we can determine that the triangle is an isosceles triangle. Which mean two angle/side are the same.
Use the Degree Angle to solve for x.
56 + 56 + x = 180
x + 112 = 180
x = 68°
Option Two: Using Law of Sine




x = 68°
