Q8 E of 59 Page 195

Let’s find whether the following measurement of each interior angle is possible for a regular polygon-

155°


We know the basic formula for the sum of all interior angles of a polygon with n sides.


Here measure of each interior angle = 155°










n = 360 / 25


n = 14.4


Since the number of sides is not a whole number, the given interior angle is not possible for regular polygon.
