The larger angle of two supplementary angles has a measure of 20° more than the measure of the smaller angle. find the number of degrees in the measure of the smaller angle.
Let smaller angle be x Let larger angle be 20 + x Sum of two supplementary angles = 180° x + 20+ x = 180° 2x + 20 = 180 2x = 180-20 = 160 x = 160/2 = 80
Smaller angle = x = 80° Larger angle = 20 + x = 20 + 80 = 100° I hope it is helpful:D
