What is the distance among the two aircraft

Reference no: EM13677275

An air-traffic controller observes two aircraft on his radar screen. The first is at altitude 1200 m, horizontal distance 18.0 km and 21.0° south of west. The second aircraft is at altitude 900 m, horizontal distance 19.8 km and 23.0° south of west. What is the distance among the two aircraft? (Place the x axis west, the y axis south and the z axis vertical.)
