To the nearest tenth, the interior angle of a regular pentagon is 108.0o In a regular pentagon, the sum of the interior angles is (5 - 2) x 1800 = 3 x 1800 = 540o In a regular pentagon, the interior angles are all the same size and are 5400 ÷ 5 = 108o which to the nearest tenth is 108.0o
900/7 = 128.6 degrees rounded to the nearest tenth
Each interior angle measures 128.57 degrees rounded
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Each interior angle will measure 162 degrees
The total number of degrees in any regular polygon is calculated by (S-2) * 180º, where S = the number of sides. So, for a hexagon the total is 4 * 180º = 720º, and the measure of each interior angle is 120º, or 1/6th of the total.

A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
Interior angles of a regular 18 gon (octdecagon) are 160o.
Only when it is a regular polygon that all interior angles are of equal measure
