 Question 119342: two angles are supplementary. One angle measures 30 less than twice the other. What are the measures of the angles?Answer by ankor@dixie-net.com(15667)   (Show Source): You can put this solution on YOUR website!"two angles are supplementary." This means the sum of the two angle = 180 degrees : One angle measures 30 less than twice the other. Let one angle = x the other angle = (2x-30) : What are the measures of the angles? x + (2x-30) = 180 3x = 180 + 30 3x = 210 x = 210/3 x = 70 degrees : The other angle = 2(70) - 30 = 110 degrees : 70 + 110 = 180 as you would expect
