A pilot flying his plane.....

1. The problem statement, all variables and given/known data
A pilot is flying his plane 48.5 km/hr northward. He has forgotten to factor in a light wind from the east, going 0.85 km/hr. At what angle should he head his plane to factor in the wind?

2. Relevant equations
I don't know :(

3. The attempt at a solution
Well, I tried using some trig functions, and I got 1 degree, but I don't think that's right, and am now totally lost. Please help!

I tried some trig too and got 1 degree west of north also... do you have any model answers at all?

i think it must be 1 degree. Just try to draw the situation, you should get right triangle and then use tan(angle)=v(wind)/v(plane). But in order to neglect the wind pilot must head his plane at north east

Thanks so much guys! I checked with my teacher and it was indeed 1 degree. I just didn't think that would make any sense, so I asked you guys. Thank you!
