Draw a sketch of the problem first using a ruler and a protractor. North would be straight up from the start point, northeast would be a 45 degree line (up from due east) to the right and west would be a horizontal line to the left. Connect the start point with the end point and you should see two triangles. Use your geometry to solve the problem with the given lengths and angles.

Good reply Doug: just a hint, no direct solution...
He is now in more trouble if he has not understood Complex numbers!

It's the vector sum of
(0 + j13)+(-7.07 + j7.07)+(-1.8 + j0)
