Answer:
See below.
Step-by-step explanation:
Graphically: the graphs of a function and its inverse are symmetric with respect to the line y = x.
Algebraically: If functions f(x) and g(x) are inverses of each other, then the composition of f and g must equal x, and the composition of g and f must also equal x.
I believe it is B. If you were to solve, you would get x=4i, x=-4i. Those are not real numbers, so if I were you I'd go with B, but you should get a second opinion.

Step-by-step explanation:
You need to remember this identity:
Observe the figure attached, where is the height in feet of the tree.
You need to calculate of the Triangle 1, where:
Substitute values into and solve for :
Now you need to calculate of the Triangle 2, where:
Substitute values into and solve for :
Then the height in feet of the tree is:
