Looking for roof help once again

I'm currently working on a chapel with kind of quirky roof line. At one end of the building the ridge height is 27'8" for about 15' with 16/12 pitch while the rest of the roof is 21'10" ridge with 8/12 pitch.

I'm hoping someone can help me figure out the correct approach to this. I have attached my chief drawing as well as 2 pdf drawings from powercad to show the look i'm trying to achieve. Any help would be greatly appreciated.

You need to draw the baseline of the 16/12 at an angle.  Just FYI, but the A-1 plan is missing a line for the valley.

 

I wish I could give you technicalities, but I just more or less kind of fiddled with it until I got the desired result.  I'm sure there's probably a mathematical way you could figure it exactly.
