The measure of an angle is 176.9°. What is the measure of its supplementary angle?

Question

An supplementary is 180 degrees and a complementary is 90 degrees

Answer 1

By definition, an angle added to its supplementary angle = 180. So given our angle is 176.9, it’s supplementary when added to it should equal 180. Preforming the calculation: 180 - 176.9 = 3.1 degrees.
