Given two sides of a triangle, you can set up an inequality using the sum and difference to show the range of possible lengths for the third side:

13 and 21

a) Set up difference and sum that shows the possible range of side lengths for the third side

- <third side (x) < +

b) Write the inequality the shows the range of lengths that could be a third side this triangle:

< x <
