An air-traffic controller observes two aircraft on his radar screen. The first is at altitude 900 m, horizontal distance 19.0 km, and 25.0° south of west. The second aircraft is at altitude 1200 m, horizontal distance 17.6 km, and 17.0° south of west. What is the distance between the two aircraft? (Place the x axis west, the y axis south, and the z axis vertical.)

2. Relevant equations

3. The attempt at a solution

my vectors for each airplane are:

<17.22, 8.03, .9>

<16.83, 13.18, 2.1>

adding them together and then getting the resultant i get 36.57 kilometers, however thats wrong and i'm not sure what i did wrong.
