Interior angle 162 Exterior angle 18 It will have 20 sides
Each interior angle will measure 162 degrees
((20 - 2) x 180) / 20 = 162 Therefore, the measure of a single internal angle of an icosagon is equal to 162 degrees.

Interior angle 162 Exterior angle 18 It will have 20 sides
Each interior angle will measure 162 degrees
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.
((20 - 2) x 180) / 20 = 162 Therefore, the measure of a single internal angle of an icosagon is equal to 162 degrees.
Each exterior angle is 18 degees Ech interior angle is 162 degrees

Each interior angle measures 162 degrees.
Each interior angle measures 162.'857142' degrees recurring '857142'
Interior angle is 180 -18 = 162 degrees because there are 180 degrees on a straight line
20 sides because the supplement of 162 is 18. 18 is the measure of each exterior angle. the measure of all exterior angles=360. So 360/18=20.
180 -162 = 18.
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°.
