Two birds sit at the top of two different trees 57.4 feet away from one another. The distance between the second bird and a bird watcher on the ground is 49.6 feet.

What is the angle measure, or angle of depression, between the first bird and the bird watcher?

30.2
59.8
40.8
49.2

Answer 1

You are dealing with opposite and adjacent sides, so you can take the tangent

Answer 2

i tried that but i didnt know how or wat to put

Answer 3

\[\tan(\theta) = \frac{49.6}{57.4}\]
Then you can take the inverse of that on a calculator

Answer 4

so i click tan then 49.6/57.4 i get 0.864

Answer 6

No, you compute 49.6 divide by 57.4 first, then take the inverse tangent with the tan^(-1) button, depending on what kind of calculator you have

Answer 7

computer calculator

Answer 8

On Windows, usually you will put in 49.6 then the division symbol '/' then 57.4, then hit the 'equal' button. Then the inverse tangent button, but I don't know where it is on the Windows calculator. But it will come out to approx. ~40.83 degrees

thank you man
