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
