Answer:
52 degrees or A
Step-by-step explanation:
Since the two sides are equal, the triangle is isosceles. This tells us that x and the other unknown angle are congruent. Because they are congruent, they are equal. The three sides of a triangle add up to 180 degrees. So, we know that 180=2x+76.
Solve this equation
104=2x
52=x
