Question

Two sides of a triangle have lengths 5 and 8. Which of the following can Not be the length of the third side.
A)6
B)3
C)5
D)4

Answer 1

A)6 that would be the answer I think

Answer 2

The sides of a triangle must satisfy the triangle equality. When it fails, it's when the sum of the two shortest sides fails to exceed the third side.

That happens here when the sides are 3,5,8 because 3+5 isn't bigger than 8.
