CB = 9

Step-by-step explanation:

To find CB, apply trigonometric function.

Reference angle = 60°

Hypotenuse = 18

Adjacent = CB

Apply CAH:

Cos 60 = Adj/Hyp

Cos 60 = CB/18

Cos 60 × 18 = CB

CB = Cos 60 × 18

CB = 9

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
