Answer 2

Q. Which of the following set of lengths can be the third sides of a triangle?

Answer:  5.5cm, 6.5cm, 8.9cm

Step-by-step explanation:

1. 2cm, 4cm, 1.9cm

using, a+b > c, a+c > b and c+b> a

= 2 + 4 > 1.9
= 6 > 1.9
= 2 + 1.9 > 4
= 3.9 < 4
⇒ hence, it cannot be the sides of a triangle

2. 5.5cm, 6.5cm, 8.9cm

using, a+b > c, a+c > b and c+b> a

= 5.5 + 6.5 > 8.9

= 12 > 8.9

= 5.5 + 8.9 > 6.5

= 14.9 > 6.9

= 8.9 + 6.5 > 5.5

= 15.4 > 5.5

⇒ hence, it can be the sides of a triangle

3. 1.6cm, 3.7cm, 5.3cm

using, a+b > c, a+c > b and c+b> a

= 1.6 + 3.7 > 5.3

= 5.3  5.3

⇒ hence, it cannot be the sides of a triangle
