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 birdwatcher on the ground is 37.4 feet.

GoldenDance:

does it have answer choices or no

loveu88:

yes

GoldenDance:

oh ok you do not give them to me

loveu88:

a. 25.5° b. 64.5° c. 28.4° d .61.6

GoldenDance:

oh ok thank you

Can you post it using the "Attach File" function, or take a screenshot of it.

lowkey:

Well send a picture

Shadow:

Ty

loveu88:

I just did it

lowkey:

SOHCAHTOA sin=opposite/hypotenuse cos=adjacent/hypotenuse tan=opposite/adjacent

lowkey:

MY POST SHADOW BYE

lowkey:

IM HELPING AGAIN

loveu88:

ok

lowkey:

Basically we do not have the angle so the easiest way is to solve for the angle and also have a graphing calculator out

loveu88:

ok thanks

lowkey:

@dude check if I'm right lol i'm kinda rusty on math math rn

dude:

Other way around for hypotenuse and adjacent Hypotenuse = 37.4 Adjacent = 17.8

lowkey:

Yes he's right lol ^

dude:

Boi everything else was right

lowkey:

So knowing this, we can solve for the angle, which for this we can use the formula cosine (x)=adjacent/hypotenuse

lowkey:

Plug the numbers in cosx=17.8/37.4 cosx=0.47593

lowkey:

however we still need to find the angle and we need to get rid of the cosine in front of it so we can use inverse cosine cos^-1(0.47593)=61.58 Which makes sense because seeing the actual triangle, the right angle is 90 and the other side seems somewhat like a 30 degree angle, but never assume

thank you so much
