You gotta use trig take the incomplete data and extrapolate from it
Answer:
AC Midpoint (2,0)-
CB Midpoint (5,-4)
midlength is 5
Step-by-step explanation:
midpoint formula 
A(2,4) C(2,-4)

(2,0)
C(2,-4) B(8,-4)

midpoint is (5,-4)
Distance between the 2 midpoints is the midsegment
(2,0) and (5,-4)


Answer:
B
