Question

If the length of two sides of a triangle are 7cm and 10cm. What can be the length of the third side.​

Answer 1

${\huge{\pink{\underbrace{\overbrace{\mathbb{\blue{ANSWER:-}}}}}}}$

We cannot find the perfect length of third side.

But a set of numbers can be found

Triangle Inequality:- The sum of two sides of a triangle is greater than the third side.

So,

third side is lesser than sum of the other sides of triangle.

third side<(7+10)

Third side<17

So the third side can be between 1 and 17

2,3,4,5,6,7,8,9,10,11,12,13,14,15,16

Answer 2

Answer-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.

Hope this help you.
