Question

the length of two sides of a triangle are 18 cm and 15 CM between what two measures should the of the third side fall​

Answer 1

Answer:

The length of the 3rd side of the wall is 30 cm.

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.
