Question

Find the length of the hypotenuse of a right triangle, the other two sides of which measure
9 cm and 12 cm​

Answer 1

Answer:

By Pythagoras theorem

AC square=AB square+BC square

AC square=81 cm+144 cm

AC square=225 cm

AC=15 cm

Answer 2

Answer:

by using Pythagoras theorem

hypotenuse^2 = side1(square) + side2(square)

hypotenuse^2 = 9^2 + 12^2

hypotenuse^2 = 81 + 144

therefore

hypotenuse^2 = 225

taking square root from both the sides

therefore,

hypotenuse = 15

(since square root of 225 is 15...)
