X= [?]°

X = 70.5º

Step-by-step explanation:

Law of Cosines

c² = a² + b² - 2ab * cosC

22² = 18² + 20² - 2(18)(20) * cosX

484 = 724 - 720 *cosX

Subtract 724 from both sides

-240 = -720 * cosX

Divide both sides by -720

0.3333333333 = cosX

X = Arccos 0.3333333333

X = 70.52877936753502

Rounded

X = 70.5º

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
