What is the value of x? explain the step process to getting to the conclusion.

x = 71

Step-by-step explanation:

Since this is an isosceles triangle, both sides are 21 units long, both angles are going to measure x at the bottom of the triangle.

The three angles of the triangle sum to 180 degrees

x+x+38 = 180

2x +38 =180

Subtract 38 from each side

2x+38-38 =180-38

2x = 142

Divide each side by 2

2x/2 =142/2

x = 71

answer: options?

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
