Answer:
Explanations:
If the sum of the measures of any two supplementary angles is 180 degrees and m
Also, if the measure of < L is sixty-six degrees less than five times the measure of < S, then:
Substitute equation 2 into equation 1 to have:
Simplify the result to have:
Add 66 to both sides of the resulting equation:
Divide both sides of the equation by 6
Get the measure of < L. Recall that:
Hence the measure of < L is 139 deg. while the measure of
