commuter air plane starts from and takes the route. first it flies into city A located 175km in direction 30¡ã north of east. next it flies 150km 20¡ã west of north cityB finally it flies 190km due west to city C . find the location C relative to location of the starting point

Answer 1

North=
175 sin 30 + 150 cos 20 + 190 *0

East =
175 cos 30 - 150 sin 20 - 190

distance = sqrt(North^2+East^2)

tan angle = North/East
note, negative, quadrant 2, angle is angle above West direction
