The measure of one angle is 38 degrees less than the measure of its supplement. Find the angle.
Let S be the measure of its supplement....so we have that
S + (S - 38) = 180 simplify
2S - 38 = 180 add 38 to both sides
2S = 218 divide both sides by 2
S = 109°
So....the angle = 109 - 38 = 71°
180/2 - 38/2 = 71
