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
