Question

The legs of a right triangle are 12 centimetres and 16 centimeters. What is the length of the hypotenuse?

A. 15 centimeters
B. 17 centimeters
C. 20 centimeters
D.28 centimeters

Answer 1

a^2 + b^2 = c^2......a and b are the legs and c is the hypotenuse
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
sqrt 400 = c
20 = c <===

Answer 2

Hope this helps you.
