If the sum of the interior angle measures of a polygon is 1440 degrees how many sides does the polygon have?
The answer is 11 sides If a polygon with 10 sides the sum of the interior angles are 1440° So 1440°+180°= 1620°
How many sides does polygon have if the interior angle measures 1440?
If the interior angle measures 1440 you have a serious problem. If the sum of the interior angles is 1440, then the question can be answered as follows: The sum of the interior angles of a n-gon is (n-2)*180 degrees So (n-2)*180 = 1440 So that n-2 = 8 and so n = 10
What is the measure of 1 angle in a 10-gon?
144 degrees; sum of interior angles in a polygon = (n-2)180 degrees. 180(18)=1440. 1440/10=144. (n=no. of sides.)
