Question

Use a trigonometric ratio to find the value of x. Round the answer to the tenths’ place.

Answer 1

Do you know about sin, cosin, and tangent and how to use them?

Answer 2

Yes.

Answer 3

I was asking @barbdewysveck1 XD

Answer 4

no

Answer 5

Sorry..

Answer 6

don't be lol

Answer 7

I figured it out! Thank you!!!!!

Answer 8

umm... didn't @barbdewysveck1 ask this question?

Answer 9

whats the answer @KayKay83

Answer 10

cos20 = 11/x @barbdewysveck1 i help u little

Answer 11

You shouldn't give or receive direct answers as they are against the CoC. @barbdewysveck1

Answer 12

but I'll happily walk you through what to do

Answer 13

I got 2x^3 + x^2 + 4x - 3

Answer 14

k just fast please

Answer 15

\[2x^3+x^2+4x-3\]

Answer 16

wrong question @BloomLocke367

Answer 17

i mean @KayKay83

Answer 18

srry @BloomLocke367

Answer 19

well you (should) know that \(\large sin=\frac{opposite}{hypotenuse},~cos=\frac{adjacent}{hypotenuse},~tan=\frac{opposite}{adjacent}\), right?

Answer 20

we are working on the problem you posted, right?

Answer 21

yep

Answer 22

okay. Do you understand what I just posted?

Answer 23

no

Answer 24

No worries.

Answer 25

well, basically, that just tells you whether to use sine, cosine, or tangent to find the missing piece. You want to start from the angle, and opposite, hypotenuse, and adjacent all are referring to the placement of the angle you're looking at.

Answer 26

That is the first triangle you have.

Answer 27

you want to be looking, first, at the angle they gave you, which is angle a. You already know the measurement now where is x in relation to a? is it the hypotenuse, is it adjacent to that angle, or is it opposite of that angle?

Answer 28

@barbdewysveck1

Answer 29

is the hypot the 11 or he longer one

Answer 30

the hypotenuse is always the side that is across from the right angle. so it's the longest one.

Answer 31

k

Answer 32

are you following me? or do I need to re-explain something?

Answer 33

im followin

Answer 34

Let f(x) = 2x^2+x-3 and g(x) = x-1. Perform the indicated operation, then find the domain. (f*g)(x)?
is my answer correct? , 2x^3 + x^2 +4x -3: domain: positive real numbers?
This was my question....so sorry for confusion!. Never mind. ;)

Answer 35

okay, so you know that side x is the hypotenuse.

Answer 36

the only other side you need to worry about is the one they gave you. is AC (11) adjacent to or opposite angle A?

Answer 37

@KayKay83, please do not post your question under somebody else's question. If you need help, open a question and you can tag me if you like and I'll help you to the best of my ability or you can find someone else to help.

Answer 38

@barbdewysveck1, are you still with me?

Answer 39

yep

Answer 40

okay. is AC opposite or adjacent to angle A?

Answer 41

adjacent

Answer 42

I apologize. New to this and trying to learn rules.. So very sorry. 1st time I have ever asked a question. Never again.

Answer 43

yep :) now look at what I told you about sin, cos, and tan and tell me which one involves the hypotenuse and adjacent side.

Answer 44

It's alright, @KayKay83 :) Welcome to OpenStudy! I'll pm you a link to the CoC.

Answer 45

@barbdewysveck1

Answer 46

@barbdewysveck1, are you still here?
