What is the value of cos C?

D. 15/8

Step-by-step explanation:

Recall, SOH CAH TOA

Since we're looking for Cos C, apply CAH. Thus:

Cos C = Adj/Hyp

Adjacent = 15

Hypotenuse = 8

Plug in the values

Cos C = 15/8

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
