Answer:

[tex]\text{C. }7.2[/tex]

Step-by-step explanation:

In the figure, all three triangles are similar. By definition, the corresponding sides of similar polygons must be in a constant proportion. Therefore, we can set up the following proportion to solve for [tex]x[/tex] by dividing corresponding sides:

[tex]\frac{x}{12}=\frac{12}{20},\\20x=144,\\x=\frac{144}{20}=\boxed{\text{C. }7.2}[/tex]
