I assume you're allowed to use sin and cos laws here, this is a trigonometry class, yes? Here we have an angle of a right triangle, and the side adjacent to it, and we need to find the hypotenuse. Since cos = adj/hyp, it's the proper one to use here:
Evaluate it with a calculator to get x = 12.04 units. Make sense?
Use the attached formula.
r = 6 / 1,200 = .005
Principal = 15,000
n = number of payments = 5 yrs * 12 months = 60
TOTAL Loan Cost = (.005 * 15,000 * 60) / 1 -(1.005^-60)
TOTAL Loan Cost = 4,500 / (1 -

Although it is NOT one of the choices, I think my answer of 17,399.52 is correct. Using a monthly loan payment calculator, I get 289.99 for the monthly payment. 290*60 months = 17,400 so that seems correct.
I do not think that formula you posted is correct. (Compare it to the one I posted.)
Answer: x=1 or x=−1
Step-by-step explanation: Step 1: Add 6 to both sides.
x2−6+6=−5+6
x2=1
Step 2: Take the square root.
x=±√1
