Answer:
We can use the triangle inequality theorem to determine the possible lengths of the third side of the triangle. According to the theorem, the length of any side of a triangle must be less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.
So, for a triangle with sides of length 16 and 17, the length of the third side must satisfy the following inequality:
17 - 16 < third side < 17 + 16
1 < third side < 33
Therefore, the length of the third side must be described by the expression:
1 < third side < 33
