    1. The problem statement, all variables and given/known data

    A sailor in a small sailboat encounters shifting winds. She sails 2.00 km east, then 3.50 km southwest, and then an additional distance in an unknown direction. Her final position is 5.80 km directly east of the starting point. Find the magnitude and direction of the third leg of her journey.

    2. Relevant equations

    3. The attempt at a solution

    Have you done any work on the problem? Try drawing it out and labeling the distances, do you know how to find the length of the sides of an isosceles (two sides same length) triangle?

    No, I haven't done anything yet. I don't know what to do. Nor solve for those sides.

    Can I get the magnitude and direction of the missing vector with that?
