Question

7. Find the measure of an interior
angle of a regular polygon having 15
side ​

Answer 1

Answer:

156 degrees

Step-by-step explanation:

each triangle has an angle sum of 180 degrees

so,the sum of the interior angles of the polygon must be 13×180

=2340 degrees. since the polygon is regular ,this total is shared equally among the 15 interior angles. each interior angle must have a measure of 2340÷15=156  degrees
