$\frac{3gallons}{1275ft^2}=\frac{7gallon}{xft^2}\\\\
cross\ multiplication:\\
3x=1275*7\\
3x=8925 \ \ | divide\ by\ 3\\
x=2975\\\\
2975ft^2\ can\ be\ covered\ using \ 7\ gallons\ of\ paint.$

In the regual nonagon shown, what is the measure of angle x?

andre [41]

The sum of the interior angles of a polygon is (n-2)*180, n being the number of sides.
a nonagon has nine sides, so the total of interior angles is (9-2)*180=7*180
this is a regular nonagon, so each interior angle has the same degrees:
7*180/9=7*20=140
the exterior angle=180-the interior angle=180-140=40
40 is the correct answer.
