  13.7

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between the angle (17°), the side opposite (x), and the hypotenuse (47).

  Sin = Opposite/Hypotenuse

Then ...

  sin(17°) = x/47

Multiplying by 47 gives x:

  x = 47·sin(17°)

  x ≈ 13.7

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
