Question

find the length of the hypotenuse of a right angled triangle if remaining sides are 9cm and 12cm.

Answer 1

⬛ TO FIND : LENGTH OF THE HYPOTENUSE
................................................................................................................✡✡✡
⏩ (HYPOTENUSE)^2 = (9)^2 + (12)^2

⏩ (HYPOTENUSE)^2 = 81 + 144

⏩ (HYPOTENUSE)^2 = 225

⏩ HYPOTENUSE = √ 225

⏩ HYPOTENUSE = 15 cm

Answer 2

by Pythagoras theorem,
hypotenuse^2 = sum of the squares of the other two sides.
hypotenuse^2 = 9^2 + 12^2
hypotenuse^2 = 81 + 144
hypotenuse^2 = 225
hypotenuse = √225
hypotenuse = 15cm
