Answer:
x = 62
Explanation:
The triangle is an isosceles triangle since the two sides are equal. The means the angles at the bases of the equal sides are the same measure.
We know the angles of a triangle add to 180
x + x+ 56 = 180
2x +56 =180
Subtract 56 from each side
2x+56 -56 = 180-56
2x = 124
Divide by 2
2x/2 = 124/2
x = 62
