Question

A bird (B) is spotted flying 6,000 feet from a tower (T)). An observer (O) spots the top of the tower (T)) at a distance of 9,000 feet. What is the angle of depression from the bird (B) to the observer (O)?

Answer 1

33.69° 41.81° 48.18° 56.31°

Answer 2

@Zale101 @HAIIll

Answer 3

@sleepyhead314 do u know any of this?

Answer 4

use inverse tangent
do you know that?

Answer 5

no..ive never done trig beofre or anything close to it

Answer 6

then why would you be doing this? xD

Answer 7

cuz they put me in geometry...

Answer 8

and its making me do trig

Answer 9

tangent of an angle = (opposite) / (adjacent)

that's a ratio, and mathematical representation of a tangent that you should memorize

do you follow that?

Answer 10

um kinda...so to find the tangent angle i just divide the opposite and ajace?

Answer 11

adjacent*

Answer 12

what I just explained was the tangent of an angle
to find the Angle using the tangent idea

you would used some calculator key that's like \(\tan^{-1}\theta \)
and plug in 9000/6000 for the weird looking zero

Answer 13

i did that...the thing came out
0.0261859215692

Answer 14

oh! be careful that you're not in radian mode!

Answer 15

um...how do i do that?...im sorry i sound like a moron....but they put me into something i have no idea about...ive never really had to use things like that on a calculator

Answer 16

it's alright, lots of people make the radian mistake xP even I do sometimes
It might depend on calculator, but you should look for a "Mode" and use the arrow keys and enter to change "Radians" to "Degrees"

Answer 17

the thing says it is in degrees

Answer 18

sadly i have 4 more questions for trig and they are all different....~im so screwed if i dont pass~

Answer 19

OH wait, you just pressed the TAN key
the way you get the angle is the TAN^(-1) key
to get to that key you might have to press the "2nd" button then the TAN

Answer 20

56.31...right?

Answer 21

yep :)

Answer 22

sweet...can u help me with the others?....or try?
