 If the angles are known, then trig is the tool. If the angles

 measure one of the angles, you can copy it using a bevel gauge or
 with a pair of dividers.

 If h is the desired height of the sawhorse and L is the length of a
 leg, then you can calculate L = h / sin 75

 I have a trig "cheat sheet" stashed away at
 http://www.iedu.com/DeSoto/CNC/trig.html that you're welcome to
 use.

 The last time I used the sine of an angle was when the HR department
 published its rules for benefit calculations.
Since you're using Outlook Express as your newsreader, I know you have
a calculator handy to make sine calculations easy.
The other easy method would be to measure the leg length on your 12"
sawhorse and do a proportion calculation, but you'd end up using the
calculator there, too.
As usual, there's more than one way to skin this cat. Choose the
method you're most comfortable with. :)
