We get the length of the hypotenuse, and the base angle. To find the length of the base, we use the cosine of 16° since it is equal to the adjacent side length/ hypotenuse side length or cos 16°= x/2500. The isolate x by multiplying both sides by 2500. The cos 16° is around 0.96126, multiplied by 2500 (cos 16°(2500)) = 2403.1
Amount of car loan taken by Scott = $5500 Amount of loan paid back by Scott = $7370 Then Amount of money paid as interest by Scott = (7370 - 5500) dollars = 1870 dollars Then Percentage of interest given for the car loan = (1870/5500) * 100 = 1870/55 = 34 percent So Scott had to pay a total interest rate of 34% in the four years.I hope the procedure is simple enough for you to understand and solve future problems.
