Question

One of two supplementary angles is seventeen times as large as the other. Find the measure of each angle.

Answer 1

x is the measure of the smaller angle, thus 17x is the measure of the larger angle.

x + 17x = 180
18x = 180
x = 10

Answer 2

That is, 10 degrees

Answer 3

x+y=180
x=17y
17y+y=180
18y=180
y=10
x=170
