Reviewing for exam-how would i find the displacement of two vectors?

[pebbles]

what if I'm given the length of two vectors and asked to find displacement? how would i find the direction?

i'm reviewing for an exam and looking over some example problems in a text i have. there are no solutions. would i find the x and y components? rx=rcos(theta) and ry=rsin(theta)?

You can't.

Were you given the angle as well as the length?

here's the problem:

a plane goes 29 meters north, and then changes direction to go east at 35 degrees for 50 meters.
