20 degrees

It is 108 degrees

An obtuse angle is a measurement of 91 degrees to 179 degrees. If it is 90 degrees, it is a right angle. If it is 1 degree to 89 degrees it is an acute. If it is 180 degrees it is a straight angle.

A right angle has 90 degrees.

The same as in a right angle which is 90 degrees

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

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

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 ):
