Answer:
x = 24
Step-by-step explanation:
The formula for determining the sum of interior angles is:
![(n-2) * 180](https://tex.z-dn.net/?f=%28n-2%29%20%2A%20180)
![4 * 180 = 720](https://tex.z-dn.net/?f=4%20%2A%20180%20%3D%20720)
Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.
![(2x+3) +(3x+12) + (7x+14) + (9x+2) + (4x+8) + (3x+9) = 720\\28x + 48 = 720\\28x = 672\\x = 24](https://tex.z-dn.net/?f=%282x%2B3%29%20%2B%283x%2B12%29%20%2B%20%287x%2B14%29%20%2B%20%289x%2B2%29%20%2B%20%284x%2B8%29%20%2B%20%283x%2B9%29%20%3D%20720%5C%5C28x%20%2B%2048%20%3D%20720%5C%5C28x%20%3D%20672%5C%5Cx%20%3D%2024)
The equation and answer above shows how to find x, which equals 24.
