The value of x in the triangle is 9.3

<h3>How to find the side x of a triangle?</h3>

The side x of a triangle can be found as follows:

The triangle ABC is similar to triangle ADE.

Therefore, corresponding sides of similar triangles are in the same ratios.

Hence,

7  / 13 = x / x + 8

cross multiply

7(x + 8) = 13x

7x + 56 = 13x

subtract 7x from both sides of the equation

7x - 7x + 56 = 13x - 7x

56 = 6x

divide both sides by 6

x = 56 / 6

x = 9.33333333333

x = 9.3
