Robin Hood is out in the woods at target practice. He is making sure he can still hit a bulls eye from 20m away. This day happens to be a very windy day, with an average wind velocity of 15m/s to the East. He can shoot his arrow with a velocity of 19m/s to the North. In order to hit the target, how many degrees off the target does he have to aim? ALso, what direction is he aiming?

If you could please show me the steps to do it, and if you want the answer, but please include steps
thanks :)
