The sum of the interior angles add up to 7200 degrees
144
Each interior angle measures 135 degrees
Each interior angle measures 160 degrees
The angle measure for each interior is 144 degrees each.Explanation: The angle measure of each interior angle of a regular decagon is 144°. Since a decagon is a 10-sided figure, replace n by 10 in (n − 2) • 180°. So the sum of the interior angle measures in a decagon is (10 − 2) • 180°, or 8 • 180° = 1440°. This is a regular decagon, so all ten interior angles are congruent. To calculate the measure of each interior angle in this regular decagon, divide 1440 by 10. The answer is 144°. 144 degrees is equal to 4/5 of 180 degrees
The sum of the interior angles add up to 7200 degrees
Each interior angle will measure 162 degrees
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line

135 Each interior angle of a regular octagon measures 135 degrees.
Each interior angle of a regular 9 sided nonagon measures 140 degrees
Each interior angle of a regular 8 sided octagon measures 135 degrees
A regular trapezoid (!) is a square. And each interior angle of a square is 90 degrees.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
It will have 14 sides and each interior angle will measure 2160/14 degrees
