Question Analysis
The primary goal is to leverage the Triangle Inequality Theorem to identify the largest whole - number length for the third side of a triangle, given the lengths of two other sides.
Key Concept Explanation
The Triangle Inequality Theorem states that for any triangle with side lengths , , and , three inequalities must hold: a + b>c, a + c>b, and b + c>a. In the context of finding the upper limit of the third side's length, the inequality c < a + b is of particular importance.
Step - by - Step Solution
1. Let and .
First, calculate : .
Also, . So, the range of the third side is 6 < c < 24.
2. Since is a whole number and must be less than
