More information is needed to answer your question.

The answer provided below is on the assumption that |AD| is an angle bisector of <BAC, by Sine rule


(sin(\angle BAD))/(24)=(sin(\angle BDA))/(36) \\ \\ \Rightarrowsin(\angle BAD)=(24sin(\angle BDA))/(36)

Also,

(sin(\angle CAD))/(18)=(sin(\angle CDA))/(x) \\ \\ \Rightarrowsin(\angle CAD)=(18sin(\angle CDA))/(x)

But,

\angle BAD=\angle CAD

Thus,

(24sin(\angle BDA))/(36)=(18sin(\angle CDA))/(x) \\ \\ xsin(\angle BDA)=27sin(\angle CDA)

But,
\angle BDA\ and\ \angle CDA are supplementary angles, hence they are equal.

Therefore, x = 27
