Question #N589

A right triangle has legs of length 5 and 12. What is the length of the hypotenuse?
A. 11
B. 13
C. 17
D. 19

Correct Answer is: B

The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs. Therefore, the length of the hypotenuse is $\sqrt{5^2 + 12^2} = \sqrt{169} = 13$.
