A triangle has one side equal to 1 foot that is 12 inches.
The second side is equal to 24 inches.
Let x denotes the length of the third side.
The third side must be less than the sum of these two sides.
[tex]\begin{gathered} x<12+24 \\ x<36 \end{gathered}[/tex]Also the third side must be greater than the difference of these two sides.
[tex]\begin{gathered} x>24-12 \\ x>12 \end{gathered}[/tex]So the possible length of the third side must be greater than 12 and less than 36.
[tex]12Options B and D are correct.The possible lengths of the third side of the triangle are
B: 19 inches
D: 15 inches
