Problema Solution

Two angles are supplementary if their sum is 180. The larger angle measures eight degrees more than three times the measure of a smaller angle. If X represents the measure of the smaller angle and these two angles are supplementary, find the measure of each angle.

if X represents the measure of the smaller angle and these two angles are supplementary then:


180 - X represents the second larger angle


the larger angle measures eight degrees more than three times the measure of a smaller angle:


180 - X = 8 + 3X


by solving we find:


X = 43 degrees

180 - 43 = 137 degrees


the two supplementary angles are 43 degrees and 137 degrees.
