State whether the following pair of
angles is supplementary, complementary, or neither. The sum of two supplementary angle
measures is 180 degrees. The sum of two complementary angle
measures is 90 degrees.
The question now is what do the two
angles we’re interested in add up to equal. When you add 39 degrees and 144
degrees, the sum is 183 degrees. This means that these two angles
are neither supplementary nor complementary.
