ANSWER:
4 units
STEP-BY-STEP EXPLANATION:
Since GH bisects CF (divides into two equal parts), we can say that CF equals twice CD. From the above we can establish the following equation:
[tex]\begin{gathered} CF=2\cdot CD \\ \\ 2y-2=2\cdot \left(3y-11\right) \\ \\ 2y-2=6y-22 \\ \\ 2y-6y=-22+2 \\ \\ -4y=-20 \\ \\ y=\frac{-20}{-4}=5 \\ \\ CD=3\cdot5-11=15-11 \\ \\ CD=4 \end{gathered}[/tex]
CD length is 4 units
