    According to the triangle inequalities rule, the sum of any 2 sides has to be greater than that of the the third side.

    We can write two inequalities to resemble this problem.

    x + 15 > 19 and 15 + 19 > x

    Now, solve for x for both inequalities.

    Steps to solve:

    x + 15 > 19

    ~Subtract 15 to both sides

    x + 15 – 15 > 19 – 15

    ~Simplify

    x > 4

    Steps to solve:

    15 + 19 > x

    ~Simplify

    34 > x

    We can put both inequalities together to get:

    4 < x < 34

    The only value from the list of options that can be “x” is 6.

    Therefore, the answer is 6cm (Option A)

    Best of Luck!
