∙ 12y agoAngles are supplementary if they add up to 180. So, with some algebra
45+x=180
x=180-45=135

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.

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 ):
