Answer:

C

Explanation:

If a line is parallel to a side of a triangle and it intersects the other 2 sides then it divides those sides proportionally.

BE is such a line , then


(AE)/(ED) =
(AB)/(BC) ( substitute values )


(9)/(5) =
(9.2)/(BC) ( cross- multiply )

9 BC = 46 ( divide both sides by 9 )

BC ≈ 5.1 ( to the nearest tenth )

Then

AC = AB + BC = 9.2 + 5.1 = 14.3
