Agata [3.3K]

Answer:

x = 48 degrees

Step-by-step explanation:

This triangle is an isosceles which means that two of the angles are the same and all triangles add up to 180 degrees so we take the two angles we know and add them

Then we subtract that number from 180 to find the third angle

180 - 132 = 48
