A child in danger of drowning in a river is being carried downstream by a current that has a speed of 2.75km/hr. The child is 0.620km from shore and 0.755km upstream of a boat landing when a rescue boat sets out. If the boat proceeds at its maximum speed of 18.4km/hr relative to the water
What angle (in degrees) does the boat velocity make with the shore?
