2x+56=180

2x=124

X=62

Answer:

x = 62

Step-by-step 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
