If <CAB is bisected by AD, then <CAD = <DAB = 20 degrees.
Therefore m<CAB = 40 degrees
tan40 = CB/24
CB = 24tan40 = 20.138cm
tan20 = DB/24
DB = 24tan20 = 8.735cm
CD = CB - DB = 20.138 - 8.735 = 11.4cm to one decimal place

<DAB = 20º, so tan 20 = DB/24; DB = 8.735
<CAB = 40º, so tan 40 = CB/24; CB = 20.138.
Finally, CD = CB - DB
