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.

180

Angles are supplementary if they add up to 180. So, with some algebra 45+x=180 x=180-45=135

90 degrees and in supplementary 180

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 ):
