Final answer:
The possible range for the third side of a triangle with sides measuring 19 in and 37 in is 18 < x < 56.
Step-by-step explanation:
The possible range for the third side of a triangle with sides measuring 19 in and 37 in is 18 < x < 56.
To determine this range, we 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. In this case, the sum of the two given sides (19 + 37) is 56, so the third side must be longer than 56 - the longest given side (37), which gives us 19. Similarly, the third side must be shorter than the sum of the two given sides (19 + 37), which is 56. Therefore, the range for the third side is 18 < x < 56.
