    11 < n < 29

    Step-by-step explanation:

    The smallest the third side can be is just bigger than the difference of the other two sides

    20-9 < n

    11
    The largest the third side can be is just smaller than the sum of the other two sides

    20+9 > n

    29 >n

    Putting this together

    11
