Question

Lines a and b are parallel.

What is the measure of angle s?

Enter your answer in the box

S=

Answer 1

22 degrees

Explanation:

The angle that measures 158 degrees and angle u are supplementary angles, meaning they add up to 180 degrees.

Angle s and angle u are corresponding angles, meaning that they are congruent.

This means that the angle that measures 158 degrees and angle s are supplementary as well. Knowing this, we can construct the following equation:

`180=158+s`

Subtract both sides by 158

`180-158=158+s-158\\22=s`

Therefore, angle s has a measure of 22 degrees.

I hope this helps!
