Question

the length of two sides of a triangle are 12 cm and 15 CM between what two measures should the length of the third side fall​

Answer 1

Answer:

The third side CA must lie between 3<CA<27cm.

Step-by-step explanation:

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.

Answer 2

Answer:

so answer is down

Step-by-step explanation:

the third side could be any length greater than 3 cm and less than 27 cm .

15 - 12 = 3 cm

12 + 15 = 27 cm
