Mathematicians drive me crazy when they make up navigation problems and get the conventions all wrong.
Wind directions generally describe the direction the air is from.
Current directions describe the direction the water flows toward.
If we do what I guess they want we can find the resultant wind velocity measured from the boat which is drifting at 12 km/hr north due to current
The boat therefore feels 12 km/hr north wind and 16 km/hr west wind
tan angle north of west = 12/16
angle north of west = 36.9 deg north of west
magnitude = sqrt (12^2+16^2) = 20 km/hr
A sail boat is acted upon a water by a current and the wind. The velocity of the wind is 16km/h from the west, and the veolocity of the current is 12km/h from thr south, find the resultant of these 2 velocitie
