Answer:
In the triangle ABC right angled at C
AB=25cm
AC=15cm
According to Pythagoras theorem
We know that,
(Hypotenuse)²=(Base)²+(height)²
=> (Base)²=(hypotenuse)²- (height) ²
=> (BC)²= (25)²-(15)²
=> (BC)²=625-225
=> (BC)²= 400
=> (BC)² =(20)²
=>BC=20cm
Therefore BC is 20cm

Answer:
(AC)^2=(AB)^2+(BC)^2
(15)^2=(25)^2+(BC)^2
225=625+(BC)^2
(BC)^2=625-225
(BC)^2=400
BC=20m
