Notice the picture below
so.... the angle of depression, is above in dashed lines.... however, the angle of depression, is identical to the angle of elevation from the water, since, both angles are "alternate interior" angles
now, using the 45-45-90 rule, then we know the swimmer is 90 feet from the lighthouse, then just use the tangent ratio to get "x"
The answer to your problem is 728

Answer:

Step-by-step explanation:
We are given the recursive formula:

This is the recursive formula for an arithmetic sequence.
The explicit formula for an arithmetic sequence is given by:

Where d=3 is the common difference.
We plug in this values to get:

We now expand and simplify to get:

We simplify to obtain:
