The hypoenuse of a right triangle is 25 cm.
We know that the difference in lengths of the other two sides is 5 cm.
Tσ Fínd :
Length of Two sides

✩Here in the Question we are given Hypotenuse of traingle 25cm i.e Shorter side. so, let the short side be 25cm. and Difference in Lengths of other two sides is 5 cm. Let the Longer side be x + 5cm. By using Pythagoras theorem We will find the Required Length of the sides of the right Triangle

Using pythagoras theorem
➢ (x)² + (x + 5)² = (25)²
➢ x² + x² + 10 = 625
➢ 2x² + 10x – 600 = 0
➢ x² + 5x – 300 = 0
➢ (x + 20) (x – 15) = 0
Now, Value of x
➢ x + 20 = 0
➢ x = -20 (Reject)
➢ x – 15 = 0
➢ x = 15
____________
∴ Length of two sides is 15 and 20cm.
