the length of two sides of the triangle is 6cm and 8cm. between which two numbers can the length of the third side fall

Answer 1

The third side must be smaller than the sum of other two sides.

Therefore, it can be anything between 1cm-13cm.

Let, the third side be x.

6cm+x cm>8cm

x cm>2cm

Now, x cannot be 1cm or 2cm.

Again,

8cm+x cm> 6cm

This means that x can be any number.

Therefore, we arrive at the conclusion that x can be anything between 3cm to 13 cm.
