If the leg lengths of a right triangle are 3 and 5 what is the hypotenuse?

To find the hypotenuse of a right triangle with leg lengths of 3 and 5, you can use the Pythagorean theorem, which states that ( c^2 = a^2 + b^2 ). Here, ( a = 3 ) and ( b = 5 ). Calculating, ( c^2 = 3^2 + 5^2 = 9 + 25 = 34 ). Therefore, the hypotenuse ( c = \sqrt{34} ), which is approximately 5.83.
