Question

the length of two sides of a triangle are 12cm and 17cm between what two measures should the third side fall
​

Answer 1

Answer:

Here in the question it is given that the lengths of two sides of a triangle are 12cm and 15cm. Since, the sum of lengths of any two sides in a triangle should be greater than the length of the third side for the formation of a triangle. Therefore, the third side should be less than 12+15=27cm.

Answer 2

Answer:

Let AB,BC and CA are the sides of triangle ABC

Given that,

Let AB=15cm,BC=12cm and Third side CA=?

Then, We know that

CA=AB−BC

CA=15−12

CA=3cm.

And

CA=AB+BC

CA=15+12

CA=27cm.

So the third side CA must lie between 3<CA<27cm.

Hence, this is the answer.
