Question

A bird sits on top of a lamppost. The angle of depression from the bird to the feet of an observer standing away from the lamppost is 35 degrees. The
distance from the bird to the observer is 25 meters. How tall is the lamppost? Draw a diagram, label it, and show how to find this value.

Answer 1

Am I doing Cos or Sin?

Answer 2

Sin

Answer 3

Is this for a trig class?

Answer 4

I have people telling me to do Cos then people telling me to do Sin. I don't know who to believe )-:

And it's for Geometry.

Answer 5

Depression

Answer 6

`I have people telling me to do Cos then people telling me to do Sin. I don't know who to believe )-:`

unfortunately it's neither of those

you use tangent

look at the drawing @legomyego180 set up

notice how with the 35 degree reference angle we have these labels

Answer 7

tan(35) = opposite/adjacent
tan(35) = h/25

solve for h

Answer 8

depression means down. its looking down

Answer 9

didnt I juust answer this

Answer 10

Yes, you did on PA but it's confusing me because I've had two, now three people tell me it's Sin then two people tell me it's Cos now its Tan?? ahh

Answer 11

Jim is correct, sorry I was thinking about a law you learn later with sine. You use Tangent indeed. I have the answer, if youd like to check with what I got.

Answer 12

OH THATS RIGHT

Answer 13

oh right `The distance from the bird to the observer is 25 meters` means we should have this instead

Answer 14

This problem is tricky lol

Answer 15

So are we still working with Tan??
