How do I use them in a brief to the Court of Appeals in Waco? I think I can use them but I'm not exactly sure how it is done.

I have not written for that Court but check the local rules http://www.10thcoa.courts.state.tx.us/about/localrules.asp
and otherwise comply with TRAP 47.7. The rule is different for the Court of Criminal Appeals. TRAP 77.3.
