Convert the percentage to a decimal:18% = 18 / 100 = 0.18Next . . .What is 18% of 162= 18% * 162 = 0.18 * 162 = 29.16
An obtuse triangle measures 162 degrees.
Exterior angle measures 18 degrees Interior angle measures 162 degrees
162 ÷ 18 = 9.
162 degrees.

180 -162 = 18.
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.
Interior angle is 180 -18 = 162 degrees because there are 180 degrees on a straight line

A supplementary angle is that which, when added to the first angle, is equal to 180°.Therefore, we know that:162 + Supplement = 180Subtract 162 from both sides, and we can see that our supplementary angle is 18°.
Exterior angles 360/20 = 18 degrees, interior 180 - 18 ie 162 degrees.
135 degrees is the supplement of 45 degrees. When you minus 45 degrees from 180 degrees you will get 135 degrees which is the supplement angle of 45 degrees.
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
60 degrees
