Answer:
   x = 10·cos(θ) -4·cot(θ)
Step-by-step explanation:
Apparently, we are to assume that the horizontal lines are parallel to each other.
The relevant trig relations are ...
   Sin = Opposite/Hypotenuse
   Cos = Adjacent/Hypotenuse
If the junction point in the middle of AB is labeled X, then we have ...
   sin(θ) = 4/BX   ⇒   BX = 4/sin(θ)
   cos(θ) = x/XA   ⇒   XA = x/cos(θ)
Then ...
   BX +XA = AB = 10
Substituting for BX and XA using the above relations, we get
   4/sin(θ) +x/cos(θ) = 10
Solving for x gives ...
   x = (10 -4/sin(θ))·cos(θ)
   x = 10·cos(θ) -4·cot(θ) . . . . . simplify
_____
We used the identity ...
    cot(θ) = cos(θ)/sin(θ)

Answer:
Step-by-step explanation:
The question is not terrifically worded. What it means is "What is the y value when x = 8" That's what f(8) conveys to you.
The answer (though zero is not marked and should be) is 1 unit above 0.
The answer is f(8) = 1 He's heading back.
