Answer:
100(x) /÷0p1
Step-by-step explanation:
t(x) factor 4
Remember "SOH CAH TOA"
Sine = (Opposite/Hypotenuse)
Cosine = (Adjacent/Hypotenuse)
Tangent = (Opposite/Adjacent)
In this case, we will be using cosine, and our equation will be 
So firstly, cross-multiply. 
Next, divide both sides by cos(28), and your answer will be 
we know that f(1)=2 so f^-1(2)=1
so B is correct!
