    How do you know what angle to use the resultant vector. How to do you know it's angle between boat and resultant velocity not the angle between current and resultant velocity.

    As the boat tries to travel at 14m/s westwards, it is dragged off course by the 8m/s current towards the north. As a result, it ends up heading theta degrees off course and with a different speed and velocity. You are looking at the difference between the path of the boat without the current and the path with the effect of the current which is theta.
