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
140
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 ):
