The supplement of an 80 degree angle is an 100 degree angle.
The supplement of an angle x is equal to 180 - x. The measure of an angle that is nine times its supplement can be written as: x = 9(180 - x) You can then solve for the measure of the angle x: x = 1620 - 9x 10x = 1620 x = 162 Therefore, that angle which is nine times its supplement is itself 162 degrees.
The supplement of a 49 degree angle is a 131 degree angle. The supplement of an angle 'x' is equal to 180-x. Two supplementary angles add up to 180 degrees.
