I need help on Relative Motion. I'm about to literally pull my hair out if I don't understand how to do this. I would very appreciate it if someone could help me out with this one problem and I probably could do the other by myself.

The pilot of an aircraft wishes to fly due west in a 50.0 km/h wind blowing toward the south. The speed of the aircraft in the absence of a wind is 205 km/h.

a. In what direction should the aircraft head?

b. What should its speed be relative to the ground?

I've spent at least 3 hours on this homework.

This is what I started out doing:

I sketched a picture of the aircraft's and wind's direction.

The plane was going west 205 km/h and the 50 km/h wind was going south. And I tried finding the displacement using the pythagorean theorem but the answer was wrong. And I divided 205 km/h over 50 km/h and used tan-1 with the anwer to get the direction but it was wrong.

I'm not even sure if I went about the problem right.
