Using Pythagoras theorem ;
⠀⠀⠀⠀
⠀⠀
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
