Answer:

3

Explanation:

The angle bisector BD makes left-side segments proportional to right-side segments. We see that CD is half of CB, so we expect the same proportion between AD and AB.

AD/AB = CD/CB

x/6 = 4/8 = 1/2 . . . . fill in the values, simplify the fraction

x = 6(1/2) . . . . . . . . multiply by 6

x = 3
