Answer:

  92

Step-by-step explanation:

  CD = DT . . . . . point D is the midpoint of CT

  7x -10 = 5x +6 . . . . . substitute given expressions

  2x = 16 . . . . . . . . . . . add 10 -5x

  x = 8 . . . . . . . . . . . . .divide by 2

Now, we can substitute this value into either expression for the length of a segment:

  DT = 5x +6 = 5·8 +6 = 46

  CT = 2·DT = 2·46

  CT = 92
