The legs of a right triangle are 18 centimeters and 80 centimeters long. what is the length of the hypotenuse

Pythagoras' theorem states that

a^2 + b^2 = c^2, where c is the hypotenuse.

To find the length of the hypotenuse, we must add together the squares of the other lengths, 18 and 80.
18^2 = 324
80^2 = 6400

c^2 = 324 + 6400 ---> Substitute these values in for a^2 and b^2
      = 6724 ---> Square root this number to find c
c    = 82

Therefore, the length of the hypotenuse is 82.

THE HYPOTENUSE IS 82 . I DID THIS PROBLEM IN MY EXAM
