Answer:

x = 52

Explanation:

The triangle is isosceles. The markings tell us that.

The 76 is not opposite either one of the equal sides. Let the angle values opposite the equal sides be x

x + x + 76 = 180 All triangles = 180

2x + 76 = 180 Subtract 76 from both sides.

2x = 180 - 76

2x = 104 Divide both sides by 2

x = 104/2

x = 52

So x = 52
