    use the pythagorean theorem: \(\large (hypotenuse)^2=(leg_1)^2+(leg_2)^2 \)

    or if you don't want to work with large numbers, notice that 48 = 16*3 and 80=16*5. they both have a common factor of 16 so just work with a leg of 3 and hypotenuse of 5... just be sure to multiply your answer by 16 at the end..

    even if one of them is correct i need to see how you got it so i can say, "yes, it's correct"
