Question 319322
a triangle have the sides of length 6 and 9. what value could the legth of the thrid side be?
<pre><b>
The sum of any two sides of any triangle is greater than its third side,

Let the third side be S

Then

1.    6 + 9 > S  or S < 15

2.    6 + S > 9  or S > 3

3.    S + 9 > 6  0r S > -3

All three triangular inequalities are met if and only if 3 < S < 15.
