a car moves 20km towards north then 35km angle of 60 degree west of north.Determine the magnitude of displacement from initial point.

Add the two vectors. I recommend adding north (y) and east (+x) components
You end up with y coordinate
y = 20 + 35 cos 60
and x ccordinate
x = 35 sin 60
The displacement magnitude is
sqrt (x^2 + y^2)
I leave you to compute that number
