Answer:
13.5
Step-by-step explanation:
The point with the missing coordinate is (?, 12), so the value of y is 12. Plug 12 into the equation in the place of y.
4x - 3(12) = 18
4x - 36 = 18
4x = 54
x = 54/4 = 13.5
A rule of polygons is that the sum<span> of the </span>exterior angles<span> always equals 360 degrees, but lets prove this for a regular </span>octagon<span> (8-sides). First we must figure out what </span>each<span>of the interior </span>angles<span> equal. To do this we use the </span>formula<span>: ((n-2)*180)/n where n is the number of sides of the polygon</span>
