8 is the hypotenuse and x is the adjacent side to the 60-degree angle. This means that you would need cosine (adjacent over hypotenuse) or secant (hypotenuse over adjacent). Cosine is not an option so it's secant.
sec 60 degrees = 8/x
Next, in a 30 60 90 triangle, you know that the side lengths are 1, 1/2 and sqrt(3)/2. So the secant of 60 degrees is 1 divided by 1/2 which is 2.
So the answer is the first question: x = 4
Wouldn't this be $90-$27 which is 63, 63 being the cost of your earrings
