a yacht is sailing at a speed of 12 knots due south in calm water.
if the tacht encounters a current of 4 knots from bearing 040 degrees:

determine the resultant speed and direction of the yacht.

here is my answers: 15.28 knots from bearing 9.69 degrees.am i right? thanks.

That's what I got, using the cosine law, then the sine law.

thanks for checking.=)
