Two geological field teams are working in a remote area. A global positioning system (GPS) tracker at their base camp shows the location of the first team as 40 km away, 18° north of west, and the second team as 30 km away, 32° east of north. When the first team uses its GPS to check the position of the second team, what does the GPS give for the following?
(a) the second team's distance from the first team
(b) the second team's direction from the first team, measured relative to due east
