Chapter 6, Problem 7CT

To determine

To complete: the blanks in the given statement.

Explanation of Solution

Given information:

The lengths of the sides of the triangle are $x,15\&21$ .

Calculation:

The third side of the triangle is greater than the difference of the other two sides and less than the sum of the other two sides.

Sum of $15\&21$ is $=21+15=36$

Difference of $15\&21$ is $=21-15=6$

Hence, x must be greater than $\underset{\_}{\text{ 6 }}$ and less than $\underset{\_}{\text{ 36 }}$ ”.
