Question

The hypotenuse of a 45-45-90 triangle has a length of 10 units. what is the length of one of its legs?

Answer 1

the length of a leg on a 45-45-90 triangle given the hypotenuse is half the length of the hypotenuse times sqrt(2)

hypotenuse = 10

 10/2 =5

 so the answer should be 5sqrt(2), which I don't see as a choice
