44^2 is not equal to 20^2 + 40^2
Thus angles u and v are not right angles
It is w because once you take the square root of the number you will see it is about 5.477 so you know that it will be closer to 5.4 because there is a two in front of the 7's.
I hope this helped :)
(123.7*10^9)/(4*10^6)=$30,925
i think thats correct
