The picture shows the Alamillo Bridge in Seville, Spain. In the
picture, mZ1 = 58°. Find the
measure of the supplement of
21.

122°

Step-by-step explanation:

Supplementary angles add to 180 degrees.

We know that ∠1 measures 58 degrees. We want to find the measure of the supplement, which we can call x. Since they are supplementary, they should add to 180 degrees.

∠1 + ∠x = 180

58 + ∠x= 180

We are trying to find the supplement, also known as x. Therefore, we must isolate x.

58 is being added to x. The inverse of addition is subtraction. Subtract 58 from both sides of the equation.

58-58+∠x=180-58

∠x=122

supplement= 122°

The supplement of angle 1 is 122 degrees.
