the boat's direction of motion. He walks at vm = 3 m/s relative to the boat.

I found the speed at which he walks in relative to the water. the speed is 6.61566 m/s. the next thing i need is at what angle to his intended path does the

man walk with respect to the water? Answer in units of degrees.

here's what i have done: i have taken the inverse tangent of the x and y components of his speed, but that doesn't work. any help would be appreciated. thanks
