Answer: 98 millimeters

Step-by-step explanation:

Since angle VTY is congruent to angle VTK, segment TY bisects angle VTK. Since Y is on segment VK, between V and K, we can use the Angle Bisector Theorem, which states that


(VY)/(YK) = (VT)/(TK) (1)

Since x= VK = VY + YK, we need to obtain VY since YK = 68.

VY is obtained by multiplying the denominator YK on both sides of equation (1). So,


VY = ((VY)(VT))/(TK) = ((68)(57))/(129.2) \\ewline VY = 30

Hence,

x = VK = VY + YK
x = 30 + 68
x = 98 millimeters
