Answer:

x equals 71

Step-by-step explanation:

Remark

All triangles have 180 degrees.

This triangle has 2 equal sides and therefore 2 equal angles.

Equation

x + x + 38  = 180           Combine the like terms on the left.

2x + 38 = 180                Subtract 38 from both sides.

2x + 38 - 38 = 180 - 38

2x = 142                        Divide by 2

2x/2 = 142/2

x = 71
