Question

Another Question Because of my sheer bottleneck in anything Mathematic

Answer 1

An observer (O) spots a bird flying at a 35° angle from a line drawn horizontal to its nest. If the distance from the observer (O) to the bird (B) is 21,000 ft., how far is the bird (B) from its nest (N)? Round to the nearest whole number.

Ill draw it out

Answer 2

Zepdrix, hi, help would be splended

Answer 3

How do we know that the nest is directly above the observer? 0_o
I don't see that in the description.
Was the picture provided for you?

Answer 4

Im a bit confused at what you saying, i drew the picture, displayed exactly as is

Answer 5

trying to find x

Answer 6

i got 12,045 but i believe that is wrong

Answer 7

I'm asking if `you drew the picture based off of the information given`,
or if the picture was provided.

Answer 8

Ahhh, im sorry, the picture was provided

Answer 9

So you said, hey, I'm trying to find the length of the side `adjacent` to this angle,
and the `hypotenuse` was provided,

so I'll need make use of Cosine, ya? :)

Answer 10

yes correct, i attempted using tan, which is why i believe the answer is wrong

Answer 11

crud, no i did use cosine

Answer 12

\[\large\rm \cos35=\frac{adjacent}{hypotenuse}\]
\[\large\rm \cos35=\frac{x}{21000}\]

Answer 13

Agree with that so far? :)

Answer 14

Mmm, alright yes i do

Answer 15

i have it written down

Answer 16

@Zeronknight i saw you attempting to write a few times, can you also help shed some light on this for me?

Answer 17

x is being divided by 21000,
so to isolate x, we'll multiply each side by 21000, ya?
\(\large\rm 21000\cos35^o=x\)

And mr calculator should do the rest for us.

Answer 18

so the cos of 35 degrees is roughly 0.819

Answer 19

divide 21000, into 0.819

Answer 20

Multiplying 21000, ya? :)

Answer 21

cosine you multiply?

Answer 22

If your calculator will allow it, try to put it all into a single line:
\(\large\rm 21000\times\cos(35)\)

Answer 23

18977.53631

Answer 24

0.819 sounds right for cos(35degrees).

21000 * 0.819 = ?

Answer 25

lol i can't figure out where you're getting these weird numbers from XD

Answer 26

ohh, whoops

Answer 27

17199

Answer 28

3 numbers off from one of the answers 17202

Answer 30

oOOoooOOOOooo...flashy

Answer 31

hehe

Answer 32

@Thatawayz I am sure Zepdrix has this covered :P. @zepdrix Thank you for helping him! It's greatly appreciated! :)

Answer 33

thanks zeron too, without that flashy text, my iq would have reached the negatives

Answer 34

LOL, your IQ will never reach the negatives.

Answer 35

-___- sometimes i feel like it has

Answer 36

Nah, we're all here to learn. Thank you for using OpenStudy! :)

Answer 37

Thankyou for being soo welcoming

Answer 38

The only reason you were a few digits off of the correct answer is because you didn't carry around enough decimals from your cosine :)

cos(35) = 0.81915204...

not a big deal though

Answer 39

No problem! If you need me I'm here for you! :)

Answer 40

ahh i see
