Question

Use a calculator to approximate the measure of the acute angle A to the nearest tenth of a degree.
tan A=1.1918

Answer 1

May I ask what grade level is this?

Answer 2

inbetween 9th and 10th

Answer 3

All it wants you to do is put arctan(1.1918) into a calculator to get A (rember arctan(tan(a))=a) so you get 50.00 degrees.

Answer 4

wat is arctan

Answer 5

arctan will be the inverse operation of the tan function. it is also written as \[ tan^{-1}(x) \] I would check your notes as there is no other way of solving this without using arctan so you would have to know it.
