Using proportions, the value of x that makes the triangle similar is of x = 14.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, we want the triangles to be similar, hence the lengths of it's sides follow the proportion given next:

$\frac{6}{12} = \frac{7}{x}$

Applying cross multiplication:

6x = 12 x 7

x = 2 x 7

x = 14.

The value of x that makes the triangle similar is of x = 14.
