Answer

To solve for z, add the equations for VC and CW (z + 13 and z + 8 respectively) and set them equal to VW (61). Solve the resulting equation to get z = 20.

To solve for z when point C is between V and W on line w, with VW = 61, VC = z + 13, and CW = z + 8, you need to set up an equation knowing that VC + CW is equal to VW.

Therefore, the value of z is 20.
