Question

12. In a 45°-45° right triangle, the length of the hypotenuse is 22 ft. how long is a leg of the triangle?

Answer 1

I'm actually wondering what i have to do as my first step?

Answer 2

if the hypotenous is 22 ft then each leg here is 22/sqrt(2) ft long
22/sqrt(2) = 22*sqrt(2)/2=11*sqrt(2)

Answer 3

IM still pretty confused though.
