Best ResponseYou've already chosen the best response.0hmm that would be the opposite side adjacent side would the touch dw:1440790695818:dw the angle now look at 27 degree angle

Best ResponseYou've already chosen the best response.0kl is adjacent of theta it's a opposite side of 27 degree angle not adj

Best ResponseYou've already chosen the best response.0Oh, yes. I forgot about the Theta,

Best ResponseYou've already chosen the best response.0to find length of x you should know one angle and one side so we would use sin function

Best ResponseYou've already chosen the best response.0Wait, how'd you get the Adjacent onto the opposite side? Is it being flipped because of the 27 degrees?

Best ResponseYou've already chosen the best response.0i know what u r talking about when you put sin(27 degree) into the calculator you will get .45399 so you should round it .45399=.4540

anonymous

Best ResponseYou've already chosen the best response.0Yes, my answer is: 74.889, which will then round to 74.89. Which is B. :)

Best ResponseYou've already chosen the best response.0what is the reciprocal of cot ?

anonymous

Best ResponseYou've already chosen the best response.0Hmm, I'm sorry haha, I don't understand this question at all, it wasn't in the lesson I got my notes from..

Nnesha

Best ResponseYou've already chosen the best response.0alright then write these down in ur notebook \[\large\rm sin \theta = \frac{ 1 }{ \csc \theta }~~~\cos \theta=\frac{ 1 }{ \sec \theta}~~~\tan \theta=\frac{ 1 }{ \cot \theta }=\frac{ \sin \theta}{ \cos \theta}\]

Best ResponseYou've already chosen the best response.0tan =1/cot or you can say it's equal to sin/cos

Nnesha

Best ResponseYou've already chosen the best response.0csc , sec and tan are reciprocal of sin ,cos and cot

Nnesha

Best ResponseYou've already chosen the best response.0so if tan = sin /cos cot = ?

Nnesha

Best ResponseYou've already chosen the best response.0what is the reciprocal of sin/cos ?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0okay so cot =1/tan \[\huge\rm tan = \frac{ 1 }{ \cot }~~and~~ \cot =\frac{ 1 }{ \tan}\]

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0if tan equal sin/cos then replace tan with sin /cos

Nnesha

Best ResponseYou've already chosen the best response.0okay so cot =1/tan \[\huge\rm \cot =\frac{ 1 }{ \color{red}{\tan}}\]\[\cot = \frac{ 1 }{ \color{Red}{\frac{ \sin }{ \cos }} }\]

Best ResponseYou've already chosen the best response.0Okay, so you're basically switching them around? With the originally formula.

Nnesha

Best ResponseYou've already chosen the best response.0just remember tan =sin/cos

Best ResponseYou've already chosen the best response.0\[\huge\rm \frac{ 1 }{ \frac{ \sin }{ \cos } } = ?\]we can change division to multiplication right

anonymous

Best ResponseYou've already chosen the best response.0I'm so confused, I'm understanding pieces but then I'm not.. As I said before, I've never seen this type of question or even demonstration in a lesson I've had.

Nnesha

Best ResponseYou've already chosen the best response.0okay let's change that to simple algebra \[\huge\rm \frac{ 1 }{ \frac{ a }{ b } }\] how would you simplify it ?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0multiply the `numerator` by the `reciprocal` of the bottom fraction \[\huge\rm \frac{ 1 }{ \frac{ a }{ b } }=1 \times \frac{b}{a}\]

anonymous

Best ResponseYou've already chosen the best response.0Why did you change b as the numerator and a as the denominator?

Nnesha

Best ResponseYou've already chosen the best response.0ohh so you don't know the definition of reciprocal reciprocal means `flip` the fraction reciprocal of 2/3 is 3/2

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0so reciprocal of a/b would be b/a so to change division to multiplication you should always multiply the numerator with the `reciprocal` of the bottom

anonymous

Best ResponseYou've already chosen the best response.0Oh okay, I understand.

Nnesha

Best ResponseYou've already chosen the best response.0so what is reciprocal of sin/cos ?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Well, you said reciprocal means to flip the fraction, so would it be cos/sin? Or would it be csc/sec?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0tan = sin/cos and cot is `reciprocal` of tan then cot would be cos/sin

Nnesha

Best ResponseYou've already chosen the best response.0\[\huge\rm cot \theta= \frac{ \cot \theta }{ \sin \theta }\]\[\huge\rm cot(10^o)= \frac{ \cos (10)^o }{ \sin(10^o) }\]

anonymous

Best ResponseYou've already chosen the best response.0Okay, I understand what's going on now. So you'd fill in the 10 degrees with the cot function?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0another example \[\huge\rm \cot (a) =\frac{ \cos(a) }{ \sin(a)}\]

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0yes you have to find cot (10 deg) which is not in the calcualtor so you should put cos(10)/sin(10)

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.0cot(10) is same as cos(10)/(sin 10)

Best ResponseYou've already chosen the best response.0It'll give me 5.671. Which is B. I'll have to review those functions more because it's still confusing but I can understand what you're saying. I'll just need to do some more practice.
