The two sides of the triangle are 9 cm and 15 cm.

\

Let the length of the third side is x.

\

According to triangle inequalities, in a triangle sum of the two sides is must be greater than the third side.

\

Sum of the two sides of the given triangle is \"\".

\

So, the length of the third side is less than 24 cm.

\

The length of the third side ranges from \"\".
