F(x) = 2(x + 6) Plug in 22 for x
F(22) = 2(22 + 6) Use the Distributive Property
F(22) = 44 + 12 Add
F(22) = 56

F(x)=2(x+6)
22=2(x+6)
22=2x+12
2x=10
x=5

Firstly, multiply both sides by S: $XS=9.4K$

Next, divide both sides by X, and your answer will be $S=\frac{9.4K}{X}$

In any triangle, the longest side is always opposite to the largest angle.
In this case, the longest the side is the side opposed to 80°
