Find the magnitude and direction of the sum of momenta of the two joggers.?

An 85-kg jogger is heading due east at a speed of 1.5 m/s. A 55-kg jogger is heading 32° north of east at a speed of 3.8 m/s. Find the magnitude and direction of the sum of momenta of the two joggers.

The magnitude is 328.4, but I can't get the angle correct for some reason! Please Help!
