Example 1:Let the measure of one of the supplementary angles be .Measure of the other angle is times .So, measure of the other angle is .If the sum of the measures of two angles is , then the angles are supplementary.So,3 a = 180 --To isolate , divide both sides of the equation by .3 a 3 = 180 -- 3 a = 60 --More items...
