Forget the degrees, for this purpose they will only cause an inaccuracy.
Here is simple:

The wheelbase of a van is close enough to call it 8 feet.  The front
crossmember is more or less on the vertical centerline of the front wheels.  The front
crossmember has to come up about 1 1/2 feet.  When jacking up the front, the
van pivots about the rear axle.  So . . . the horizontal centerline of the
front wheel has to be at an elevation 1 1/2 feet higher than that of the rear
wheel.  Or, the van has to be on a 3 in 16 gradient.
