A
North and east are perpendicular directions hence we can use them as the basis of our coordinate system. The coordinates of this point can then simply be represented as
P = 1.4 N + 4.8 E (km)
The magnitude can be given by the right triangle formula :
P = [tex]\sqrt{N^2 + E^2}[/tex]
= 5 km
Direction = atan(N/E) = 16.3 deg north of east = 73.7 deg east of north
