Answer:

  x = 98 mm

Step-by-step explanation:

The angle bisector divides the triangle into proportional parts.

  VY/VT = KY/KT

  VY = VT(KY/KT) . . . . solve for VY

What we really want is VY + KY, so we can form that sum as ...

  VY +KY = KY(VT/KT) +KY

  x = KY(1 +VT/KT) = (68 mm)(1 +57/129.2)

  x = 98 mm
