Best ResponseYou've already chosen the best response.3\[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\] that's all you need to find all 6 ratios

Best ResponseYou've already chosen the best response.0I got 9^2+2^2=c^2, 81+4=c^2, c^2=85,sqrt(85)=c

Best ResponseYou've already chosen the best response.3looks good dw:1443972735567:dw now use the definition iposted above to write sin cos and csc

Best ResponseYou've already chosen the best response.0for cos of B I got 9(sort)/85

Best ResponseYou've already chosen the best response.3looks good and we don't have to rationalize the denominator

Best ResponseYou've already chosen the best response.0and for cscB i'm not sure what that would be

Best ResponseYou've already chosen the best response.3what's the reciprocal of sin ??

Nnesha

Best ResponseYou've already chosen the best response.3like cos and sec are reciprocal cos theta = 1/sec theta

Best ResponseYou've already chosen the best response.0so csc(b)=85/2sqrt(85)?

Best ResponseYou've already chosen the best response.0@sana9 the original definitions were not those which nnesha gives you. please keep in mind that you might have a question like what is sin of 360? you will never find a 360 degrees in a triangle. so the standart school definitions will not work for such question. so keep in mind these universal things: Sinus: sin(a)=(yb)/R Cosine: cos(a)=(xb)/R Tangent: tg(a)=(yb)/(xb) picture : https://upload.wikimedia.org/wikipedia/ru/thumb/8/8f/Trig_functions.gif/250pxTrig_functions.gif sourse `wikipedia`

Best ResponseYou've already chosen the best response.3i know they are asking for sin but what is sin B = ?

Nnesha

Best ResponseYou've already chosen the best response.3look at this definition \[\large\rm cos \theta =\frac{ 1 }{ \sec \theta}\]\[\sin \theta = \frac{ 1 }{ \csc \theta } \]\[\tan \theta =\frac{ 1 }{ \cot \theta }\] or tan theta = sin/ cos

Nnesha

Best ResponseYou've already chosen the best response.3so if you find sin B you can easily find csc B

anonymous

Best ResponseYou've already chosen the best response.0for csc(b) I believe it's 85/2sqrt(85)

Best ResponseYou've already chosen the best response.3sin = opposite over hypotenuse so sin B =?

Best ResponseYou've already chosen the best response.0ok so let me try one more time :)

Best ResponseYou've already chosen the best response.3dw:1443973622264:dw right

Nnesha

Best ResponseYou've already chosen the best response.3right so what's sin B = ???

Nnesha

Best ResponseYou've already chosen the best response.3right what about tan a ??

Nnesha

Best ResponseYou've already chosen the best response.3so what is the exact value of tan A ?

anonymous

Best ResponseYou've already chosen the best response.0so I have another question regarding find sin cos and tan

anonymous

Best ResponseYou've already chosen the best response.0this involves side length so I was sure how to work this out!

Nnesha

Best ResponseYou've already chosen the best response.3no it's not 1 remember tan = sin over cos and sin = opposite over hyp cos = adjacent over hyp \[\huge\rm tan = \frac{ \frac{ o }{ h } }{ \frac{ a }{ h } }=\frac{o}{h} \times \frac{h}{a}\] multiply top fraction with the reciprocal of the bottom fraction \[\huge\rm tan =\frac{o}{\cancel{h}} \times \frac{\cancel{h}}{a}=\frac{o}{a}\] o=opposite a=adjacent so tan = opposite over adjacent

Best ResponseYou've already chosen the best response.3np so what is tan A ?? :+)

Nnesha

Best ResponseYou've already chosen the best response.3dw:1443974262921:dw remember opposite and adjacent sides depends on angle 9 is adjacent side of angle B but 9 is opposite side of angle A adjacent side that touches the angle we are looking at

Best ResponseYou've already chosen the best response.3good ! cot =2/9 cot and tan are reciprocal of each other i think u got it just need more practice :=)

Best ResponseYou've already chosen the best response.0:) thanks so much. I'm sure how to solve angles and length when knowing only 2 side lengths in a right triangle

Nnesha

Best ResponseYou've already chosen the best response.3good then did you try to find 3rd side ? :=)

Nnesha

Best ResponseYou've already chosen the best response.3same question like last one one given are the 2 legs of `right triangle ` then always you can use Pythagorean theorem to find 3rd side

Best ResponseYou've already chosen the best response.0it's just finding the angles which confuses me :/

Nnesha

Best ResponseYou've already chosen the best response.3ah i see dw:1443974659273:dw just focus one angle A for this question its easy to find angle bec u know all 3 sides you can use any ratio doesn't matter u will get the same answer!

Best ResponseYou've already chosen the best response.3let's pick sin sin A = opposite over adjacent what is opposite and adjacent side of angle A ?

anonymous

Best ResponseYou've already chosen the best response.0I thought sin was opposite over hyp

Best ResponseYou've already chosen the best response.3right lol sorry mistake thinking about tan

Nnesha

Best ResponseYou've already chosen the best response.3right \[\huge\rm sin A = \frac{ 8 }{ 17}\] when we have to find anlde we use invs sin \[\large\rm A = \sin^{1} \frac{8}{17}\]

Nnesha

Best ResponseYou've already chosen the best response.3let me check :D wait plz

anonymous

Best ResponseYou've already chosen the best response.0and to find angle B we would do sin(B)=15/17 which is sin1(15/17)=61.9 and it's exactly 62?

Best ResponseYou've already chosen the best response.3right you can round it if you want or if the direction says so

Nnesha

Best ResponseYou've already chosen the best response.3ohh wait directions is NO DECIMAL so round it

anonymous

Best ResponseYou've already chosen the best response.0the direction just mentions the exact measure

Best ResponseYou've already chosen the best response.0i'm having trouble inputting the degrees sign into the answer

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.3i guesss you don't have to put degree sign bec it says angle A so definitely the number u will put is an angle hmm i think ....

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0it's wanting the degrees symbol :/

Nnesha

Best ResponseYou've already chosen the best response.3hmmm does it work \[\huge\rm a^o\] i'm not sure how to put on that website

Nnesha

Best ResponseYou've already chosen the best response.3is it a practice website or online school documeent ?

anonymous

Best ResponseYou've already chosen the best response.0this is what showed up

Nnesha

Best ResponseYou've already chosen the best response.3hmm well i think the answer we got is correct not sure what theyyy want us to do did they gave u the correct ??

anonymous

Best ResponseYou've already chosen the best response.0It makes sense in terms of the math, but when I enter it in the system it's didn't recognize it

Nnesha

Best ResponseYou've already chosen the best response.3ye right let me think hmmm

Nnesha

Best ResponseYou've already chosen the best response.3how did you put degree sign ?

Nnesha

Best ResponseYou've already chosen the best response.3i mean degree how did you put little 0 ? :P

anonymous

Best ResponseYou've already chosen the best response.0I did option shift and then 8

Nnesha

Best ResponseYou've already chosen the best response.3maybe they just want us to write the number like 28 and 62

anonymous

Best ResponseYou've already chosen the best response.0I tried that but it was incorrect I think they want me to show that it's degrees

Nnesha

Nnesha

Best ResponseYou've already chosen the best response.3oh okay please let me know what was the mistake :=)

anonymous

Best ResponseYou've already chosen the best response.0:) I think it's just something that has to do with the keys I don't think it's the actual math
