What is a proportion?

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

Since the triangles are similar, the lengths are proportional. Researching the problem on the internet, we have that the proportions are given as follows:

  • A side with a length of x is proportional to a side with length 25.
  • A side with a length of 3 is proportional to a side with length 15.

Hence:

[tex]\frac{x}{25} = \frac{5}{25}[/tex]

Simplifying the denominators:

x = 5.
