Question

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

Answer 1

Step-by-step explanation:

9²+12²=?

81+144=?

225=?

15=?

so the length of hypotenuse is 15

Answer 2

Answer:

15 cm

Step-by-step explanation:

By Pythagoras theorem:

H² = P² + B²

= H²= 9² + 12²

= H² = 81 + 144

= H = √225

= H = 15

thus,  hypotenuse = 15 cm
