Question

Find the measure of an interior angle of a regular polygon having 15 sides.

Answer 1

to find the total lengthof 15 sided polygon we have to use (angle sum property )

angle sum property = n=15

(n-2)×180

(15-2)×180

13×180

2340

now

to find meaure of an interior angle = total measure of polygon / no. of sides = 2340/15

=156

therefore, 156 is the measure of an interior angle of 15 sides
