Final answer:
The missing information in the inequality that represents the possible values for the perimeter, p, of the triangle is 25 + 10 < p < 25 + 60. The possible values for the perimeter are between 60 cm and 110 cm.
Step-by-step explanation:
The missing information in the inequality that represents the possible values for the perimeter, p, of the triangle is:
25 + 10 < p < 25 + 60
Since the triangle has sides measuring 25 cm and 35 cm, the third side length, s, must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore, the possible values for the perimeter, p, of the triangle are between 60 cm and 110 cm.
