Answer:
A
Step-by-step explanation:
Since AD is an angle bisector then it divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{AC}{AB}[/tex] = [tex]\frac{CD}{BD}[/tex] , substitute values
[tex]\frac{AC}{8}[/tex] = [tex]\frac{3}{6}[/tex] ( cross- multiply )
6AC = 24 ( divide both sides by 6 )
AC = 4 cm → A
