Question

Given that the triangles shown below are similar, what is the value of x?

Answer 1

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

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:

$\frac{x}{25} = \frac{5}{25}$

Simplifying the denominators:

x = 5.
