    Step-by-step explanation:

    Rule for the sides of a triangle:

    The sum of the two smallest sides of a triangle must be greater than the biggest side.

    In this question:

    Sides of 6, 21 and x. We have to find the range for x.

    If 21 is the largest side:

    Two smallest are 6 and x.

    x + 6 > 21

    x > 21 - 6

    x > 15

    If x is the largest side:

    Two smallest and 6 and 21. So

    21 + 6 > x

    27 > x

    x < 27

    Then

    x has to be greater than 15 and smaller than 27. So the answer is:

    15
