notice the 45-45-90 rule

the hypotenuse is whatever the other 2 sides are, since they're equal, times \(\bf \sqrt{2}\)

Answer 2

\(\bf hypotenuse = x\sqrt{2} \implies3\sqrt{2}\times \sqrt{2}\)

Answer 3

I'm a bit confused. Does that mean the other side will be 3√2? Or 3√2 * √2?

Answer 4

ah, i see. therefore its 6. thank you!

Answer 5

yeap
