A plane flies from base camp to lake A, a distance of 280km at a direction of 20.0 degrees north of east. After dropping off supplies, the plane flies to

lake B, which is 190km and 30.0 degrees west of north from lake A. Graphically determine the distance and direction from lake B to the base camp.


Using the component method (you can use this to chech your answer in your graphical method): Rx= 190cos30° + 280cos20° = 427.66 Ry= 190sin30° + 280sin20° = 190.77 So, to get your resultant: sqrt(427.66^2 + 190.77^2) = 468.28 km For the direction: W of S
