There some variables that you left out, like the RUN of your first set of rafters.
I found this online calculator that can figure it for you. All you do is enter your measurements and it will calculate it for you

You are probably better off ordering the trusses pre made and delivered to your specs, but if you want to do it the old way you need to figure your rise multiplied by 12 divided by your run which is 1/2 your span. If you have a speed square it has the angles marked for you.

Along with stone, mud and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials.

I dont believe there are any "set angles"... what I do is lay out the roof on the floor with a chalk line... and get the look your after...
