    nope, not possible

    In any triangle, the sum of any of the two sides must be greater than the third side

    7+8 is not greater than 15, it is equal to 15

    Try by making 15 the base, and then drawing the 7 and 8 inch sides above it.
    They will lie flat on the base line, thus no triangle.
