Jagger Shelton · Answer 1

less than 29

Step-by-step explanation:

The smallest side cannot be smaller than the difference of the other two sides

18-11 = 7

and it cannot be larger than the sum of the other two sides

18+11 = 29

Let s be the other side

7 < s < 29

Aydan Bird · Answer 2

It must be less than 29 units in length.

Step-by-step explanation:

The length of the third side of a triangle must be less than the sum of the lengths of the first two sides. Since 11+18=29, the third side must be less than 29 units in length.
