\underline{\textsf{Given:}}

\textsf{D bisects CE and}

\mathsf{CD=x+6,\;DE=4x-21}

\underline{\textsf{To find:}}

\textsf{CD}

\underline{\textsf{Solution:}}

\textsf{Since D bisects CE, we have}

\mathsf{CD=DE}

\mathsf{x+6=4x-21}

\mathsf{6+21=4x-x}

\mathsf{3x=27}

\implies\mathsf{x=9}

\textsf{Now, CD = x+6 = 9+6 =15}

\underline{\textsf{Answer:}}

\textsf{Length of CD is 15 cm}
