Answer:

Step-by-step explanation:

The 2 smaller triangles are proportionate to one another because they are 2 parts of the same larger triangle. Setting up the proportion, one triangle at a time:

[tex]\frac{x}{8.3} =\frac{11.6}{6.7}[/tex] and cross multiply to get

6.7x = 96.28 so

x = 14.37 or 14.4, choice A.
