a^2+b^2=c^2
a^2+9=25(5*5)
therefore ,a^2=25-9=16
√16=4
sides are 4 cm,3 cm,5 cm
a^2+9=25(5*5)
therefore ,a^2=25-9=16
√16=4
sides are 4 cm,3 cm,5 cm

Given :
length of hypotenuse (c) = 5cm
And one side (a) = 3cm
Let,
third length of the side = (b) cm
As we know that ,
Pythagoras theorem
(a)² + (b)² = (c)²
=> (3)² + (b)² = (5)²
=> 9 + (b)² = 25
=> (b)² = 25-9
=> (b)² = 16
=> b = 4
Hence, length of the third side of the triangle = (b) = 4 cm.
So,
The sides of the right angled triangle are 3cm , 4cm and 5cm.
