(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ship cruises forward at Vs=5 m/s relative to the water. On deck, a man walks diagonally toward the bow such that his path forms an angle theta = 22 degrees with a line perpendicular to the boat's direction of motion. He walks at Vm = 2 m/s relative to the boat

The speed he walks relative to the water is 5.749 m/s.

At what angle to his intended path does the man walk with respect to the water? Answer in degrees.

2. Relevant equations

I was thinking maybe of using Tan-1(opposite/adjacent)

or some thing to that effect

3. The attempt at a solution

Tan-1( but what is the opposite and adjacent?

Would it be 22 degrees? But 22 degrees is perpendicular to the boat's direction.

hmmm help please
