    Answer: (2) 4

    Explanation:-
    The length of a side must be less than the sum of the other two sides.
    Then, X < (10 + 6.5)
    X < 16.5 cm

    The length of the side must be greater than the difference between of the other two sides.
    Then, X > (10 – 6.5 )
    = X > 3.5

    Therefore, we have two limits for the value of X .
    Then, 3.5 < X < 16.5

    Then, the value of X will be between 3.5 and 16.5.
    the value of the X = 4 cm.

    Hence, the answer is (2) 4.
