It is an angle of 162 degrees.
An angle that measures 162 degrees would be considered an "obtuse" angle. This is because anything above 90 degrees is obtuse while anything below is acute.
Each exterior angle is 18 degees Ech interior angle is 162 degrees
162 degrees
Interior angle is 180 -18 = 162 degrees because there are 180 degrees on a straight line
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°.
Interior angle 162 Exterior angle 18 It will have 20 sides
It is an angle of 162 degrees.
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
An angle that measures 162 degrees would be considered an "obtuse" angle. This is because anything above 90 degrees is obtuse while anything below is acute.
((20 - 2) x 180) / 20 = 162 Therefore, the measure of a single internal angle of an icosagon is equal to 162 degrees.
162
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
Assuming every interior angle is the same, and they're all 162 degrees, the shape would have 20 sides.
n is the number of sides and interior angles are 162 deg so 90(2n - 4)/n = 162 ie (180n - 360)/n = 162 ie 162n = 180n - 360 ie 18n = 360 so n = 20.
