|B==================Angle A
The ramp is between angle A and a.  That is the hypotenuse.  The side a is the opposite. 
sin A=a/hypotenuse.
sin 3.5 deg=a/36
a=36 sin 3.5=2.2 inches
--------------------
For AB, it is the tangent, opposite (2.2) over adjacent (unknown)
tan 3.5=2.2/AB
AB=2.2/tan 3.5=36 to nearest tenth.  A side is not equal to the hypotenuse, however, because to two decimal places it is 35.97 in.</PRE>
