`\sf{\bold{\green{\underline{\underline{Solution}}}}}`

⠀⠀⠀⠀

Using Pythagoras theorem ;

⠀⠀⠀⠀

`\sf{\red{\boxed{\bold{( hypotenuse )^2 = ( base )^2 + ( height )^2 }}}}`

⠀⠀

First , lets understand the concept ;

⠀⠀

What is Pythagoras theorem ??

⠀⠀⠀⠀

• In Pythagoras theorem the square of hypotenuse is equal to the square of base in the square of corresponding height when one angle is 90° .

⠀⠀⠀⠀

What is hypotenuse ?

⠀⠀⠀⠀

• The side in the front of right angle is known as hypotenuse .

⠀⠀⠀⠀

In the given Δ ;

⠀⠀⠀⠀

Hypotenuse = DB = 25 cm

⠀⠀

Acc. to the formulae ;

⠀⠀⠀⠀

➠ 25² = 24² + d²

⠀⠀⠀⠀

➠ d² = 25 ² - 24 ²

⠀

➠ d² = 625 - 576

⠀⠀⠀⠀

➠ d² = 49

⠀

➠ d = √49

⠀⠀⠀⠀

➠d = 7cm

⠀⠀⠀⠀
