A sheet of paper is in the form of a triangle ABC in which AB=3, BC=4 and CA = 5. D is a point in AB such that AD = 1

The paper is folded so that C coincides with D and the resultant crease meets BC at the point X.

Find the length of BX.

I looked at 12/8 a couple of times--yep, that reduces to 4/3.  I  hate to think I have to start using the calculator for everything.
