Answer:
x = 66 degrees (just type the 66)
Step-by-step explanation:
All triangles have their angles add up to 180 degrees.
We know that one of the angles is 48 degrees. Also, since this triangle is an isosceles triangle (a triangle with 2 equal sides), the other two angles have to be the same.
First let's subtract 180 and 48.
180 - 48 = 132
Since 132 is the sum of the other 2 angles, we would have to divide it by 2 (since they're congruent to each other)
132 ÷ 2 = 66
Thus saying x = 66
