Question

Which regular polygon's interior angles measure a total of 720 degrees?

Answer 1

We know that
The formula to find the sum of the interior angles of a regular polygon is
(n - 2)*180°
where n is the number of sides
so
clear n
(n - 2)*180° = 720°-----> (n-2)=720/180---> n-2=4----> n=6 sides

the answer is
6 sides
