I have 1/sqrt(10), 3/(sqrt(10)), 3/sqrt(10). I cannot understand why this is not the answer. It is pointing in the same direction.

The velocity of a boat is 20km/hr in a direction 50 degrees north of east. The wind velocity is 5 km/hr from the west. The resultant velocity of the boat can be represented by the side of a triange...
