Using proportions, it is found that the value of x is of x = 5, hence option A is correct.
<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.
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:

Simplifying the denominators:
x = 5.
