    Yes, it would be a scalene triangle. This can happen.

    The Triangle sides have to be greater than c.

    a+b > c

    With the given inches, substitute it into the equations:

    a = 3 in

    b = 5 in

    c = 9 in

    3 + 5 > 9

    Solve.

    9 > 9

    This is False since because a + b is not > c. a + b is equal to c.
