   Get a big stack of lumber and keep trying until you get it right.

   Or use trig.  (Admit it, your math teacher did tell you it would be useful, but you didn't believe her.)

   Set the bevel on the saw to 45degrees.

   Calculating a backed hip

     H= rise, A=run, C= rafter length (the hypotenuse)

   rip angle= sin-1(H/((sqrt2)*C))

   "sin-1" is the inverse sin, but I don't know how to type super scripts here. The attached image shows how it should be written.

   this also works for finding the rip angle for the corner miters  on a hollow tapered column.

   Note: in my previous reply with the equation, use the dimensions of a common rafter, not the actual hip rafter.
