5. (b) Can it be an interior angle of a regular polygon? Why?
The measure of an interior angle is 22°
Regular polygon has all interior angles equal.
Let number of sides and number of interior angles be n.
Sum of interior angles of a polygon =
Sum of interior angles of a polygon = =
Number of sides of a polygon should be integer but since it is not a integer .So, it cannot be an regular polygon with interior angle as 22
