    Rule:

    longest side has to be less than the sum of the other 2 sides

    if we assume that 23 is longest

    9+?≤23

    minus 9 both sides

    ?≤14

    if we assume that 23 is not the longest

    9+23≤?

    32≤?

    BUT

    the triangle changes

    and the longest side is changing because when one becomes shorter, there is a new longest

    so therefor the legnth is any number from 14 to 32, not including 14 or 32

    23cm. If the remaining side were 9cms in length, it wouldn't be long enough to connect the other two sides.
