Q: A hexagon has interior angles measuring (in degrees) 137, 100, 150, 114, 90, and x. What is the value of x?
 
 Answer: 129
Explanation:
The total measure of all the interior angles in a polygon is (n-2) * 180, where n is the number of sides of the polygon.
A hexagon has 6 sides, so n = 6. The total is (6-2) * 180 = 720.
Add up the five given angle measures: 137 + 100 + 150 + 114 + 90 = 591.
The measure of the remaining angle is 720 – 591 = 129.
My TI-84 Plus program POLYGON will find this total for you.

Q: What is the sum of the interior angles of a convex hexagon?
 
 Answer: 720
Use the formula (n-2)x180, with n=6 (because a hexagon has 6 sides).
(6 – 2) x 180
4 x 180
720
