the sonar of a navy cruiser detects a submarine that is d=4601 ft from the cruiser. the angle between the water level and the submarine is 0=32 degrees. What formula should I use to solve?

depends on what you want to find.

The depth of the sub is

d/4601 = sin32°

Looks like you need to review your trig ratios

Thanks Steve, taking a physics course for credit this summer, but I am going in to 9th grade and have not had trig yet. Thanks for the formula!
