Question

find the interior angles of a regular polygon with 15 sides.

Answer 1

if n is the sides of polygon,

then sum of all interior angles is (n-2)180

one angle is [(n-2)180]/n

here n=15

(n-2)=15-2=13

[(13)180]/15

=156

one interior angle is 156degree

and sum of all angles is 2340degree
