Question 998750: The sum of the measures of four interior angles of a 5 sided convex polygon is 450 degrees. What is the measure of the fifth angle? Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! A polygon is a multi-sided geometric figure whose sides are straight lines.
A 5-sided polygon is called a pentagon.
--------------------------
Regardless of the measure of each angle, one of the characteristics of pentagons is that the total of the angles sum 540. If four of your pentagon's angles add up to 450, the 5th angle measures:
540-450= 90 degrees
