Question

help

Answer 1

Remember SOHCAHTOA?

Which identity (SOH CAH TOA) relates adjacent sides with the hypotenuse?

Answer 2

it's cah

Answer 3

Good!

Answer 4

\[\cos(\theta) = \frac{adj}{hyp} = \frac{14}{26}\]REmember what I told you about finding the ange?

Answer 5

angle*

Answer 6

you said to find the adjacent and hypothnuse. right?

Answer 7

mmhmm, and what would they be?

Answer 8

hyp - 26 adj - 14

Answer 9

Yes, exactly what I have posted above too :) Good.

Do you remember what I said to do next?

Answer 10

\[\theta=\cos ^{-1}(\frac{ 14 }{ 26 })\]

Answer 11

<_<

Answer 12

x3 i believe you said to simplify it

Answer 13

Yeah :) plug the function @Nurali stated into your calculator using degrees andnot radians.

Answer 14

ok

Answer 15

But what I had said to do in the ast problem we worked on was to the the inverse functions of both sides, that way you could derive the \(\theta\) value

Answer 16

alright

Answer 17

I ended up getting an answer that's not on there, would it end up being choice 4?

Answer 18

Im finding the angle fine.

Answer 19

are you using a scientific calculator?

Answer 20

I'm using https://www.mathway.com/problemwidget.aspx?affiliateid=affil18092

Answer 21

use this. https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&es_th=1&ie=UTF-8#q=scientific+calculator&spell=1

Answer 22

I did, I got the same answer that I did on the other site

Answer 23

Click on the radians so the degree side is exposed

Answer 24

ok

Answer 25

If I am able to work it, I believe you can also :)

Answer 26

ok but just a question, how am supposed to enter the information into the calculator

Answer 27

press "INV" \(\rightarrow\) \(\cos^{-1} \rightarrow \) 14 \(\div\) 26

Answer 28

it leaves me with 57. 42 so would it be c?

Answer 29

*b, 57

Answer 30

yes :)

Answer 31

Finally, good job~

Answer 32

x3 sorry it took so long, I'm kinda tired, but I'm awake now, mainly because I just dropped the laptop on my face and scare myself

Answer 33

lol.
