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.

Setting up the perpendicular bisector to CD has X meet CB 1.5 units from B, so BX has length 1.5.
