Answer:
Both options (15 and 19) are possible length of the third side.
Explanation:
Given a triangle with one side that measures 1 foot and another side that measures 24 inches.
The measure of the third side must be greater than the difference between the two sides given and less than the sum of the two given sides.
[tex]\begin{gathered} (24-12)>x>(24+12) \\ 12>x>36 \end{gathered}[/tex]The length of the third side could be any number greater than 12 but less than 36.
From the two given options. Both of the options (15 and 19) falls within the interval.
Therefore, both options (15 and 19) are possible length of the third side.
