    Step-by-step explanation:

    By the converse of Pythagoras' identity.

    If the longest side squared equals the sum of the squares of the other 2 sides then triangle is right.

    longest side = 15

    15² = 225

    4² + 9² = 16 + 81 = 97 ≠ 225

    Thus sides do not represent a right triangle.
