Answer and Step-by-step explanation:
This problem requires the use of trigonometric functions, specifically the tangent trig function.

Plug in the values.

Multiply by x to both sides, then divide by tan(40) to both sides.

Now, plug this into a calculator and rounded to the nearest whole number (foot).
x = 9534.0287
x = 9534 ft.
The answer is 9534 ft., the last option.
