two birds sit at the top of two different trees 17.8 feet away from one another. The distance between the first bird and a bird watcher on the ground is 37.4 feet. What is the angle measure, or angle of depression, between this bird and the bird watcher?

hold on

Height of bird = 17.8 True (slant) distance from watcher to bird = 37.4 Angle theta = asin(17.8/37.4=28.4 degree

your like saving my life. haha can you answer one more ?

Using ∡C of △CBA shown below, create three different trigonometric ratios using sine, cosine, and tangent. You will need to create your own angle and side measures for this task. For full credit, please provide both the ratio and work used to solve for a missing piece of the triangle. Round all solutions to the nearest hundredth.
Hero
  • Hero
You can create your own triangle
Hero
  • Hero
Actually, you should probably draw the triangle first
anonymous

got to my profile and look for the same ? every thing is there
anonymous
  • anonymous
did it help
Hero
  • Hero
I don't know why she didn't just draw the triangle
Hero
  • Hero
In order to help you, you need to draw it
anonymous

hahaha shush. idk how i would word it though. there was so much going on

You could have made it look a little prettier than that sunset

its beautiful .. belongs in a museum
anonymous
  • anonymous
yes now 3^2 + 4^2 sholed = the other side
Hero
  • Hero
Okay sunset :D
anonymous
  • anonymous
whats the three different trigonometric ratios using sine, cosine, and tangent?
Hero
  • Hero
Well, if we use sunset's approach:
anonymous
  • anonymous
cos is a/h
Hero
  • Hero
|dw:1325124890880:dw|
anonymous
  • anonymous
tan is o/a and sin is o/h
anonymous
  • anonymous
dont use the ABC ONES they change if the tryangle is BAC or CAB use what i put
Hero
  • Hero
She has to use them because they are part of the problem. It has to be in terms of triangle CBA
anonymous
  • anonymous
no afince Hero but i tryed doing it that way and it mest me up
Hero
  • Hero
It doesn't mess everyone up
anonymous
  • anonymous
ok but remember it dont always aply just with this problim
anonymous
  • anonymous
lol im so confused on this part here For full credit, please provide both the ratio and work used to solve for a missing piece of the triangle. what should i put for that ? it has to be in words
Hero
  • Hero
tahtah, I know you're taking a test
anonymous
  • anonymous
ik you know im taking a test.
anonymous
  • anonymous
ok you have to fined the tangent , cosine, and sine
Hero
  • Hero
You have to find the angles tahtah
anonymous
  • anonymous
sine is opposite/hypotenuse
anonymous
  • anonymous
cosine is adjacent/hypotenuse
anonymous
  • anonymous
how do i find the angles ? i understand the cos and sin thingy now.
Hero
  • Hero
you have to take the inverse of the ratios
anonymous
  • anonymous
tangent is opposite/adjacent
anonymous
  • anonymous
u fined the angles using sin cos and tan
Hero
  • Hero
sunset, she has to take the inverse of those ratios
anonymous
  • anonymous
yes my bad but its still using it
Hero
  • Hero
\[\sin^{-1}(\frac{3}{5})\]
anonymous
  • anonymous
yes
Hero
  • Hero
\[\cos^{-1}(\frac{4}{5})\]
Hero
  • Hero
\[\tan^{-1}(\frac{3}{4})\]
anonymous
  • anonymous
trust hero hes smart
anonymous
  • anonymous
thank you :) your smart too sunset.
anonymous
  • anonymous
thank u good luck
anonymous
  • anonymous
so i just solve that & it will be the angle?
Hero
  • Hero
You have to find the other two angles
Hero
  • Hero
Once you find angle A, you can use the sums of triangles = 180 rule to find the remaining angle.
anonymous
  • anonymous
mmm would it be .64?
Hero
  • Hero
make sure you're in DEGREES, not radians
anonymous
  • anonymous
ahhh . so 64 degrees? haha
Hero
  • Hero
Just make sure your calculator is in degrees first.
anonymous
  • anonymous
omg now i got .92 ik thats wrong. i see why my teachers hate me
Hero
  • Hero
:/
anonymous
  • anonymous
if you just get me the angle for A i can do the rest.
Hero
  • Hero
A = 36.87
anonymous
  • anonymous
saved me. thanks so much man : )
Hero
  • Hero
You should probably figure out how to use your calc. You're lucky you get to do your test at home. Not every student is so lucky.
anonymous
  • anonymous
i know :| geo. just isnt my thing
Hero
  • Hero
It could be if you wanted it to be

hold on, where's the answer for the original equation?
