The value of x is 8 from the diagram given.

How do you calculate the sides of similar triangles?

The corresponding sides of a similar triangle are said to be in proportion if and only if the corresponding angle are also equal.

To calculate the side of line x (|x|), we have to determine the ratios of the corresponding sides as:

$\mathbf{\dfrac{BC}{DC} = \dfrac{AC}{EC}}$

$\mathbf{\dfrac{x}{10} = \dfrac{12}{15}}$

x = 120/15

x = 8

Therefore, we can conclude that the value of x is 8.
