Question

which equation would you use to find how high the airplane is flying?

Answer 1

options
A. cos 31= x/ 4872
B. tan 31= 4872/x
C. tan 31= x/4872
D. cos 31= 4872/x

Answer 2

Ooooh this is a fun question. Love these. You would use a trigonometric ratio, a tangent in this case. So you would get out your texas instrument calculator, but first write this on a piece of paper: tan(31) = Opposite / Adjacent, which would be H for height over 4872. You would multiply both sides by 4872 and get 4872 times tan(31) = H. Type that into your calculator, and you should get 2927.4 nearest tenth feet.
