An aircraft travelled from Calabar to Kano as follows:it flew to Imprint covering a distance of 300km ,30degrees west of North and then flew 400km 60degrees.

Answer 1

do it the same way as the previous one. However angles are left of y axis

Answer 2

(north) component = 300 cos 30 + 400 cos 60
(west) component = 300 sin 30 + 400 sin 60
again sqrt (north^2+west^2)
angle west of north = tan^-1 (west/north)
subtract from 360 to get compass angle, add to 90 to get math text angle

Answer 3

500km
