The answer is 41.41
Since we know the side that is opposite to a, and the hypotenuse, we have enough information to get the cosine of a. The cosine is 45/60. If we know the cosine of an angle, we can get the arccos of that value to get the angle. The arccos of 45/60 is about 41.41.

In this question, they gave you the system of equations. You just need to use the two of them.
We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.
If we know the m form of f, we can convert the second equation and find the answer:
Plug in the m value of f:
Distribute the 5:
Subtract -75 from both sides:
Combine like terms:
Divide both sides by -2:
So, we learned that the number of the multiple-choice questions is 12.
