from the latest national Mathcounts competition comes a question I have no idea how to attack:

You are given a scalene trapezoid whose side lengths I don't recall. 

A circle with its center on the longer base is tangent to the two legs but not to the other base. 

How on earth would you calculate the distance from the center of the circle to either end of that base?
