Subject: Problem

Hi Annie,

This just came across from a source at UGA. As I am having trouble posting to
the forum, I thought this might be a good place to post and get some responses.

I am having a problem that I am needing some help with. I teach hs precalculus
and am coach of the UIL math team. One of the problems we had on the last
test has stumped me and I need to learn how to work it in case we run into
another one like it. If anyone can and will help me with the following problem
I would appreciate it. Thanks. I need more than the answer. I need to know
how to work it and/or where to go to learn how to work it.

Given a triangle with sides 5, 6, and 7, what is the radius of the incircle?

Can you post it and see if we can get any responses.
