Question

lengths of two sides of a Triangle are 4 cm and 9 cm. Between which two numbers can length of the third side fall?​

Answer 1

Answer:

Between 5cm and 13cm.

Step-by-step explanation:

Let the third side be x.

Since, in a triangle, the sum of the lengths of two sides is always greater than the third side, x + 4 > 9, x + 9 > 4, and 4 + 9 > x.

x + 4 > 9 implies x should be greater than 5 and

4 + 9 > x implies that x should be lesser than 13.

Therefore, 5 < x < 13.
