Question

plz answer fast it is urrgent ​

Answer 1

This sum can be solved by using Pythagoras theorem:

As in this sum triangle ABC is right angled at C so the formula for this is

AB²=AC²+BC².

we want only BC so the formula be

BC²=√AB²-AC².

let us see the sum using the above mentioned formula

Step-by-step explanation:

$given \\ ac = 25cm \\ ab = 7cm \\ bc =x \\ x = \sqrt{ {25}^{2} } - {7}^{2} \\ x = \sqrt{625 - 49} \\ x = \sqrt{576} \\ x = 24cm$
