You can put this solution on YOUR website! Find the measure of an angle such that the difference between its supplement and 2 times its complement is 70°
x = the angle
180 - x = its supplement {supplementary angles add up to 180°
90 - x = its complement {complementary angles add up to 90°}
180 - x - 2(90 - x) = 70 {difference between its supplement and 2 times its complement equals 70°}
180 - x - 180 + 2x = 70 {used distributive property}
x = 70 {combined like terms}
