Question

Find the number to sides of a regular polygon if the sum of the interior angles are 7560

Answer 1

Use S=(n-2)180 
S is the sum and N is the number of sides
If you know that the sum is 7560 then plug that in for S
7560=(n-2)180
Then solve for n
7560=180n-360 (note I used distributive property)
7560+360=180n
7920=180n
7920/180=n
n=44 sides
I hope this helps :)
