third side?
(1) 19 cm
(2) 17 cm
(3) 13 cm
(4) 3 cm

Please help me to solve this question​

Answer 1

Answer:

3) 13 cm

Step-by-step explanation:

The Sum of Any two sides of triangle is always greater than length of third side. For example

Let ABC is a triangle. And AB, BC and AC are the three sides of Triangle.

So,

(AB + BC) > AC or

(AB + AC ) > BC or

(AC + BC ) > AB

It means,

(7 + 10) > Third side.

In other words,

Third side < 17.

But there is option less than 17. So, required answer would be 13 cm

Answer 2

Answer:

13 cm

Step-by-step explanation:

sum of two sides should be greater than the third side.

Here

7+10 is greater than 13

13 + 10 is greater than 7

13 + 7 is greater than 10

other option dont satisfy this condition.
