A supplementary angle is 180 degrees. So, it depends how many supplementary angles you add together.
Each interior angle measures 144 degrees* * * * *No! The sum of the exterior angles of a polygon is always 360 degrees - no matter how many sides, So the extrior angle of a regular dodecagon is 360/12 = 30 degrees. Since the interior and exterior angles are supplementary, the interior angle is 180-30 = 150 degrees.
90 Degrees.
An obtuse angle is an angle measuring between 90 and 180 degrees
Each exterior angle is 360/8 = 45 degrees. So each interior angle is 180 - 45 = 135 degrees.
90 degrees
140
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
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 ):
