A spotlight on a boat is y = 2.5 m above the water, and the light strikes the water at a point that is x = 9.5 m horizontally displaced from the spotlight (see the drawing). The depth of the water is 4.0 m. Determine the distance d, which locates the point where the light strikes the bottom.

2. Relevant equations

3. The attempt at a solution

I believe this is just a simple geometry problem? Or will it run into trouble.

Maybe some help to get it going and the idea of what to do.
