Here you need to draw a force system.
The car is the center and you have mainly two forces: velocity and gravity.
The angle they ask you for is the same angle formed by the velocity (mass* acceleration) and the gravity (mass*gravity)
And to know the angle you need to do the tangent.
Tg∡=
Both masses canceld and
Tg∡=
∡=arcTg 0.30
∡=187.35°
