Question

If the hypotenuse of a right angled triangle is 25 CM if one of the remaining two sides is 15 cm find the length of its third side

Answer 1

Answer:

20 cm

Step-by-step explanation:

Let the 3rd side be X cm,

According to Pythagoras Theorem-

==> (Hypotenuse)² = (Perpendicular)² + (Base)²

25² = 15² + X²

625 = 225 + X²

625 - 225 = X²

400 = X²

X= √400

X = 20

Length of the third side = 20 cm.
