I have no idea what "due" means in this context.
I also do not know if the wind is blowing FROM 120 (navigation way) or TO 120 ( land way).
and I do not know if your angles are measured clockwise from North (navigation way) or counterclockwise from the x axis(math way)
An aeroplane is moving at 200 km/h due 60.The plane experiences a wind blowing at 120 due 210.Find the resultant velocity of th
e plane by resolving the velocities into their components.

All angles are measured CW from +y-axis.
Vr = 200km/h[60o] + 120km/h[210o].
X = 200*sin60 + 120*sin210 =
Y = 200*Cos60 + 120*Cos210 =
Vr = sqrt(X^2 + Y^2).
TanA = X/Y.
Vr = 200km/h[60o] + 120km/h[210o].
X = 200*sin60 + 120*sin210 =
Y = 200*Cos60 + 120*Cos210 =
Vr = sqrt(X^2 + Y^2).
TanA = X/Y.
