Divide the number of sides into 360 degrees and then subtract your answer from 180 degrees to give you the interior angle.
For example a regular hexagon has 6 equal sides and 360 divided by 6 = 60 degrees (the exterior angle)
180 - 60 = 120 degrees (the interior angle)

Each interior angle will measure 162 degrees
A regular polygon with each interior angle measuring 120 degrees is a hexagon.
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
