Answer:

No triangles

Explanation:

we know that

The Triangle Inequality Theorem, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

so

In this problem

5+7 > 15 ------> is not true

therefore

No triangles can be constructed with the given side lengths
