How many sides would there be in a convex polygon if the sum of all but one of its interior angles is 1970 degrees?
+36915 Formula for a n-gon sum of interior angles (n-2)(180)
(n-2)(180) > 1970
n > 12.94
n =13 as a convex polygon has angles < 180 degrees example: n= 14 would = 2160 which is 190 more than 1970
