ivettef365 · Answer

the formula to find the measure of the angles is (n-2)180

ivettef365 · Answer

so you have 900, to go backwards on the formula first divide 900/180 then add 2

anonymous · Answer

The formula for the sum of the measures of the interior angles of a regular polygon is (n-2)180. Set this equal to 900 and solve for n to find the number of sides in the polygon. 
900 = 180(n-2)
900 = 180n - 360
180n = 1260
n = 1260/180
n = 7
