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°
