if the legs are 60 and 80 cm, what is the hypotenuse

Using the Pythagorean theorem, the hypotenuse (c) can be calculated as follows:

c^2 = a^2 + b^2

c^2 = 60^2 + 80^2

c^2 = 3600 + 6400

c^2 = 10000

Taking the square root of both sides:

c = √10000

c = 100 cm

Therefore, the hypotenuse is 100 cm.
