Question

If two sides of a triangle are 5 and 12 inches long, what's the range of possible lengths for the third side?

Answer 1

Answer:

$7$

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

$a+b>c, a+c>b \ and \ b+c>a$

$a+b>c$

$5+12>c$

$17>c$

$a+c>b$

$5+c>12$

$c>7$

Combine both inequalities

$c7$

$7$
