a+b>c
where a,b and c are the sides of a triangle
Sum of two sides of the triangle will always be greater than the 3rd side.
So, in option E substitute x=3
Then the sides are
1, 4, 5
1+4=5
Sum of two sides of the triangle will always be greater than the 3rd side.
Which is not true for option E
So, E is the Answer.
but for option E , when sides are 1,4 and 5
5+4=9>1 , means this rule valid in one case of this triangle.
kindly explain where I'm lacking the main concept , thanks
if a, b and c are three sides of a triangle then all three of these inequalities should be true
