I'm having trouble with this one problem:
A plane flies from base camp to lake A, 280 km away, in a direction of 20.0 degrees north of east. After dropping off supplies it flies to lake B, which is 190 km at 30.0 degrees west of north from lake A. Graphically determine the distance and direction from lake B to the base camp.
Well, I began by drawing the two paths making an angle of 30 facing west. Drawing the third path to make a triangle, I then find the vector x and y components. After I get all my numbers and finish calculating, I get an answer of close to 400 km and 50 degrees south of west. However, the book gives an answer of 310 km at 57 degrees south of west. Any guidance or suggestions as to what to do?
