Pretty easy relative velocity question but I suck at Physics. I wanted to check my diagram and if it is not right than ask for help on a mathematical aproach because mine is not working.(adsbygoogle = window.adsbygoogle || []).push({});

The question is: An airplane, who air speed is 600 km/h, is supposed to fly in a straight path 35.0 degrees north of east. But a steady 100 km/h wind is blowing from the north. In what direction should the plane head?

It's not artistic but I hope it's understandable. The angle between the black arrow from origin and either vertical or horizontal is what I need to find. By the way: not to scale.

Answer at back of book is: 42.9 degrees N of E

This is the beginning of my approach which probably doesn't follow all math rules and is therefore ridiculous.

600cosA = xcos35

600sinA - 100 = xsin35

Thanks for any help or hints or links on how to do math or anything.

If no one answers before 7:00AM PST tomorrow don't bother because I'll check the solutions book at school.
