Concept explainers
To find: The least possible whole number that is the measure of the third side.
Answer to Problem 9PT
The least possible whole number measure is
Explanation of Solution
Given: The measure of the two sides of a
Here, we use the concept of triangle inequality.
By the triangle inequality,
The sum of the lengths of any two sides pf a triangle must be greater than the third length of the third side.
Hence,
The given sides are
Let the third side be
Now check the inequality,
Hence, the option C is correct as the least possible whole number is
Therefore, the least possible whole number measure is
