Find Force Vector (30N) as Cartesian Vector

[kahless2005]

I need to find the Forve Vector (30N) as a Cartesian vector.

Given the information given, I believe that the angles of the Triangle are: 90, 32.37, and 57.63. This gives the projected vector in the x, y plane as 16.1 N.

The answer should be : - 13.2i - 17.7j + 20.3k.

Help?
