Question

What would you make the size of one of the sides of a right triagle if its other side is 12cm and the hypotenuse is 20cm?

Answer 1

hi how do u ask a question

Answer 2

16 cm

Explanation:

i would use the pythagorean theorem:

find the sum of the square of the legs and set that equal to the square of the hypotenuse

a² + 12² = 20²

a² + 144 = 400

subtract 144 from each side:

a² = 256

a = √256

a = 16
