Question

an aircraft travelled from calabar to kano it flew first to illorin covering a distance of 300km at 30 degree west of north then flew 400km 60 degree of east of north to kano what is the resultant vector
All angles are measured CCW from +x-axis.
D = 300km[120o] + 400km[30o].
X = 300*Cos120 + 400*Cos30 = 196.4 km.
Y = 300*sin120 + 400*sin30 = 459.8 km.

D = sqrt(X^2 + Y^2).
Tan A = Y/X.

A =
