5. A plane flies from base camp to Lake A, a distance of 280 km at a direction of 20.0 degrees north of east. After dropping off supplies, the plane flies to lake B, which is 190 km and 30.0 degrees west of north from Lake A.
I'm not even going to write the actual question part, since that's not the issue I'm having. Basicaly, I'm having trouble drawing the vector 30.0 degrees west of north.
I know how to draw a vector North or south of East or west, but the reverse of that can't get through my head. I tried, and I ended up getting 225 km from Lake B to the camp, but the key says 310. My scale is set at 1 cm=50 km, and my vector for camp to Lake A is 5.5 cm (about) at the correct angle. Maybe just a picture to tell me the correct direction?

Just to check a second question:
2. An airplane flies 200 km due west from city A to city B and then 300 km in the direction of 30.0 degrees north of west from city B to city C. In striaght-line distance, how far is city C from city A and in what direction is City C in relation to city A?
485 km 20 degrees N of W.
