Answer 1

Great job!

And thank you thank you THANK YOU for being one of the few people who understands the concept of homework HELP. You provided not only the math problem, but your answers as well and asked people to help make sure you got them correct, not to do them for you. THANK YOU!!!! There should be more students like you!

Answer 2

Lol, human beings have mentioned like numerous answer. ok in a 40 5-40 5-ninety triangle, the hypotenuse is sqrt(2) situations each and each leg. So consequently merely do 3 * sqrt(2) * sqrt(2) this is the comparable as 3*2 this is 6. So selection E is genuine. the only different people who have been on condition that answer used pythagorean theorem. this is too lots pointless artwork! desire this helps!

Answer 3

All correct. Don't forget the meters on 7-9.
