A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
160 The 2 angles must equal 180 degrees, so 160 is the answer.

A supplementary angle is a 180-degree angle minus the number of degrees in the given angle.
135 degrees. Supplementary angles add up to 180 degrees so the supplementary to 45 is 180 - 45 =135.
160 The 2 angles must equal 180 degrees, so 160 is the answer.
180
90 degrees and in supplementary 180
20 degrees
Angles are said to be supplementary when they add up to 180 degrees.
A supplementary angle is 180 degrees. So, it depends how many supplementary angles you add together.
Well a Right angle is 90 and a supplementary is 180. Complementary, I'm not sure ):
