Answer:
x = 28°
Step-by-step explanation:
You can realize looking to this triangle that it is an isosceles triangle, so it means that the two angles at the bottom have the same size.
76° + 76° = 152°
The sum of the internal angles of a triangle are always 180°
You subtract 152° from 180° and get the value of x:
180° - 152° = 28°
