Problema Solution
One polygon has three more sides than another. How many degrees are in the sum of the interior angle measures of the first polygon?
Answer provided by our tutors
The sum of the interior angles of a simple n-gon is (n − 2)π radians or (n − 2)180 degrees.
so, if for other polygon,there are 3 more sides then,
sum=(n+3-2)180 degrees
or (n+1)180 degrees
