Vector word problem...?
The summit of a mountain, 2340 m above base camp, is measured on a map to be 4160 m horizontally from the camp in a direction 30.8 degrees west of north. What are the components of the displacement vector from camp to summit? Choose the x axis east, y axis north, and z axis up.
I got x = -3439.5, y = 2340, z = -4160 ... but it's wrong 
How did you approach this, and what answers did you get?

-z is down +z is up.
