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.

Answer:
I think the answer is x = 13/3
Step-by-step explanation:
F(4) is function notation that means the value of y when x = 4.
Replace x with 4 in the expression and evaluate the right side.
f(x) = 3x - 15
f(4) = 3(4) - 15
f(4) = 12 - 15
f(4) = -3
