If the sum of the interior angles of a regular polygon measures up to 720 degrees, then how many sides does the polygon have?
Choose the correct choice
A) 10	B) 6	C) 12	D) 11	E) 14
one of the interior angle = 180 - 360/n   sum of the interior angles is = n (180 - 360/n)   given   n(180 - 360/n)=720   180n - 360 = 720   180n = 1080   n = 1080/180=
