Respuesta :

I get 89.22, use the tan^-1 function on a graphing calculator and plug in 73.

Answer:

The answer is 89.22 because when you type it in the calculator you get 73.45158967 ≈ 73.

Those were my answer chose:

tan(81.61)= 6.780175001 ≈ 7

tan(64.61)= 2.106944081 ≈ 2

tan(60.61)= 1.775438564≈2

tan(89.22)=73.45158967 ≈ 73

And plus I picked 89.22 on the test and got it correct.
