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? http://learn.flvs.net/webdav/assessment_images/educator_geometry_v14/pool_Geom_3641_0402_06/image0034e2daa34.gif answers 30.2 59.8 40.8 49.2
You are dealing with opposite and adjacent sides, so you can take the tangent
i tried that but i didnt know how or wat to put
\[\tan(\theta) = \frac{49.6}{57.4}\] Then you can take the inverse of that on a calculator
so i click tan then 49.6/57.4 i get 0.864

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
computer calculator
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
