Question

Solve for x................

Answer 1

x = 17

Explanation:

Use the interior angle sum theorem which says:

if n is the number of sides the sum of the interior angles is 180(n-2)

there are 6 sides, so the interior angle sum is 180(6 - 2) = 180 * 4 = 720.

This means that if you add all the angles you will get 720, so:

`110 + 8x - 1+5x+36+116+7x+19+6x-2=720`

`26x+278=720\\26x = 442\\x = 17`
