Question 697454: Find the measure of an angle that is 30 degrees less than its suppplement
Answer by algebrahouse.com(1659) (Show Source): You can put this solution on YOUR website!
x = the angle
180 - x = its supplement {supplementary angles add up to 180�}

x = 180 - x - 30 {angle is 30� less than its supplement}
x = 150 - x {combined like terms}
2x = 150 {added x to each side}
x = 75� {divided each side by 2}
