Answer :

Given:

There are given two triangles.

Explanation:

According to the question:

We need to find the tall of Ariadne.

So,

To find the value, we need to use triangle proportion properties.

So,

Suppose the value of tall is x.

So,

[tex]\frac{x}{6}=\frac{15}{18}[/tex]

We need to find the value of x.

Then,

[tex]\begin{gathered} \frac{x}{6}=\frac{15}{18} \\ x\times18=15\times6 \\ x=\frac{15\times6}{18} \\ x=5 \end{gathered}[/tex]

Final answer:

Hence, the solution is 5 ft tall.
