Answer:

[tex]7<c<12[/tex]

Step-by-step explanation:

 two sides of a triangle are 5 and 12 inches long

The sides of triangle a= 5  and b = 12

To form a triangle

[tex]a+b>c, a+c>b \ and \ b+c>a[/tex]

[tex]a+b>c[/tex]

[tex]5+12>c[/tex]

[tex]17>c[/tex]

[tex]a+c>b[/tex]

[tex]5+c>12[/tex]

[tex]c>7[/tex]

Combine both inequalities

[tex]c<12, c>7[/tex]

[tex]7<c<12[/tex]
