Question

If the quadrilateral below is a trapezoid, solve for x.
X =

Answer 1

x = 7

Explanation:

Angle S and angle V are supplementary angles which means their sum is equal to 180°.

We can write the following equation to find the value of x based on the above mentioned information:

8x - 21 + 145 = 180

• Add/subtract like terms

8x + 124 = 180

• Subtract 124 from both sides

8x = 56

• Divide both sides by 8

x = 7
