Answer 2

Answer:

The length of third side of triangle is 15 cm.

Step-by-step-explanation:

We have given that,

For a right angled triangle,

Hypotenuse = 25 cm

One side = 20 cm

We have to find the length of third side.

Let the length of third side be x cm.

We know that,

In right angled triangle, by Pythagoras theorem,

( Hypotenuse )² = ( One side )² + ( Third side )²

⇒ ( 25 )² = ( 20 )² + x²

⇒ 625 = 400 + x²

⇒ x² = 625 - 400

⇒ x² = 225

⇒ x = √( 225 )

⇒ x = √( 15 * 15 )

⇒ x = 15 cm

∴ The length of third side of triangle is 15 cm.
