Answer 1

Answer:

9Cm

Step-by-step explanation:

Using Pythagorean Theorem

=

$\sqrt{ {15}^{2} - {12}^{2} }$

$\sqrt{225 - 144}$

$\sqrt{81}$

= 9Cm

Hope this helps you ❤

Answer 2

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

$\bf CA = AB - BC$

$\bf CA = 15 - 12$

$\bf CA = 3 cm.$

And

CA = AB + BC

CA = 15 + 12

CA = 27cm.

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

Hence, this is the answer.
