A river has a current flowing with a velocity of 2.0 meters per second due east. A boat travels at 3.0 meters per second relative to the river and is headed due north. In the adjacent diagram, the vector starting at point P represents the velocity of the boat relative to the river water. What is the direction of the resultant velocity relative to the south riverbank? 12 degrees
34 degrees
56 degrees
78 degrees
