26

Reason: From the correspondence A↔X, Y↔Y, B↔Z the similarity scale factor is k = XY/AY = YZ/YB = XZ/AB. The condition AY = AX implies the image of A under the dilation/rotation about Y is at distance twice AY, so k = 2. With AY = 12 and AB = 5, triangle AYB is a 5-12-13 right triangle, so YB = 13. Hence YZ = k·YB = 2·13 = 26.
