Answer:
C
Step-by-step 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
=
( substitute values )
=
( 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
