@iasdyuhasd In and incline, the car has a component of its weight parallel to the road and opposite in direction to the static friction. For the car to remain at rest, this component of the weight must be cancelled by the friction acting upward. You can set this relationship in a mathematical form and the find the angle that makes v=0.
