Given the lengths of two sides of a triangle, find the range for the length of the third side (between what two numbers should the length of the third side be). Write the inequalities for each case. 8 and 13

5 < third side < 21

Step-by-step explanation:

Let the length of the third side be .

We know that must be smaller than the sum of the lengths of the two other sides. Thus .

We also know that

And

So, in conclusion, .
