Question 307555
Find the measure of an angle such that the difference between the measures of its supplement and three times its complement is 10 degrees.
.
Let x = angle
then
complement is 90-x
supplement is 180-x
.
From:"the difference between the measures of its supplement and three times its complement is 10 degrees"
(180-x) - 3(90-x) = 10
180-x - 270+3x = 10
180 - 270+2x = 10
-90+2x = 10
2x = 100
x = 50 degs
