A boat which travels 23.9 mi/hr at full throttle in still water is headed due north in a river that flows from west to east with a current of 6.3 mi/hr. If the boat is crossing the river at full throttle, find the bearing of the true course of the boat.
---
tan(bearing) = 23.9/6.3
---
bearing = tan^-1(23.9/6.3) = 75.23 degrees
