Question

If the lengths of the legs of a right triangle are 5 and 12, what is the length of the hypotenuse?

Answer 1

Answer: 13

Reasoning:
1) a^2 + b^2 = c^2
2) replace the variables:
(5)^2 + (12)^2 = c^2
3) 25 + 144 = c^2
4) 169 = c^2
5) square root of both sides equals the final side length (the hypotenuse) which is 13
