Question

For what value of x is line / parallel to line m in this figure?

Answer 1

132

Explanation:

The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180

This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180

So x = 180 - 48

180 - 48 = 132

Hence, x = 132
