Question

8. Find the length of the unknown sides in the following right-angled triangle

15 cm
12 cm​

Answer 1

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:

(AB^2)+(BC^2)=(AC^2)
