Let's use the triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

So, to find the range of possible lengths for the 3rd side, we calculate as follows:

13 - 5 < x < 13 + 5
8 < x < 18

Therefore, the possible lengths for the 3rd side of the triangle could be any value between 8 and 18 inches.

Apologies for the mistake. Let's correct it:

According to the triangle inequality theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, the two given sides are 5 inches and 13 inches. Let's denote the length of the third side as x. So, according to the theorem:

5 + 13 > x
18 > x

Also, the third side must be shorter than the sum of the two given sides:

13 + x > 5
x > 5 - 13
x > -8

Combining both inequalities, we get:
-8 < x < 18

Therefore, the possible lengths for the 3rd side of the triangle lie in the range of -8 and 18 inches. However, since lengths cannot be negative, the 3rd side must be greater than 0. Hence, the possible length for the 3rd side is between 0 and 18 inches.
