Do you know law of sines?

- anonymous

i couldn't do it on this

- anonymous

yes, you can to find the angle x.

x=sin-1(.0087679 then what do i do

- anonymous

Umm, that decimal is incorrect.

Guys you cant use the law of sines on a triangle that's not 90 degrees angle, right????

- anonymous

Looks to me like\[c^{2} = a^{2} + b^{2} - 2bc CosA\]

- anonymous

Correct me if I'm wrong; please - Is that triangle a right angle??

- anonymous

i have no clue what do u think brittini

- anonymous

nd no its not a right angle

- anonymous

Law of sines is not only for right triangles.

- anonymous

You cant use law of cosines, and I think if you were to try @ScottB05 's setup is incorrect.

- anonymous

Ok, you still cant use the law of cosines.

- anonymous

but how do i start in this problem

- anonymous

I would say since the angles in a triangle must add to 180 degrees. Find your missing angle.

- anonymous

|dw:1355439236917:dw|
Again - Please tell me if I'm going about this the wrong way?

- anonymous

Oh.... Right ignore me completely you made a mistake apparently - I'm so stupid sometimes -.-

- anonymous

im confused

- anonymous

I still disagree with @ScottB05

- anonymous

With good reason, I said I'm wrong already xD

- anonymous

Oh, okay. :p

- anonymous

now u think its solved by the law of cosines

- anonymous

No, I think law of sines

- anonymous

okay srry but lets start from the beginning because i got messed up with all this srry brittini

- anonymous

No prob.

- anonymous

thnxs k

|dw:1355440194446:dw|

- anonymous

So, since you know two angles..can you find the third one? Hint: all angles in a triangle add up to 180 degrees

- anonymous

63 degrees

- anonymous

Great, so now your triangle looks like: |dw:1355440610624:dw|

- anonymous

:-( can u show me the equation to help solve it

- anonymous

You can use law of cosines.

x=1924.7 its so off

- anonymous

what did u get brittni

- anonymous

@Brittni0605 You've done what I've done way up
My answer to that equasion was x = 26.9

- anonymous

i know but i did something wrong

- anonymous

wait actually u did the wrong problem this is the right one |dw:1355443147072:dw|

- anonymous

can u try to solve it and see what u get

- anonymous

|dw:1355443262333:dw|

- anonymous

thats much better thnxs i really understood my mistake

- anonymous

I may still be wrong but I believe this to be correct. Right until proven wrong =)

- anonymous

i think its the right answer

- anonymous

oops, sorry guys, I was eating.

- anonymous

hhh its alright so i think we got the right answer

- anonymous

I'd be happier if @Brittni0605 double checked my answer - I was wrong before :)

- anonymous

what do u think brittni

- anonymous

Hm, this is interesting. The picture must be drawn incorrectly, two angles are equal so it has to be an isosceles triangle.

- anonymous

its not exactly the same as the assignment but im new in this drawing thing

- anonymous

|dw:1355444759541:dw|

- anonymous

maybe that's better..

- anonymous

yup way better :p

- anonymous

I agree with thinking x= 9.56

- anonymous

thnxs people i will close the question and i really appreciate ur help

- anonymous

Yep, np.

- anonymous

|dw:1355445651964:dw|Hmm... Wait actually... Haha I just saw something cause u drew it like that

- anonymous

Hmm..

- anonymous

Umm, cosine would be adjacent over hypotenuse, not hypotenuse over adjacent.

- anonymous

|dw:1355446061993:dw|Of course :L

- anonymous

Hmm, and for the original triangle..xsin54 = 8sin63, x= 8.81

- anonymous

So looks like we found a solution, x = 8.81; after about 2 hours? :)

- anonymous

Lol, phew, I feel so dumb.

- anonymous

hhh really its hilarious so THE ANSWER IS 8.81 for sure :p

- anonymous

Yes, I agree. Sigh.

- anonymous

Well in Scotland it's 1.10 am; I can sleep happy knowing it's solved! :)

- anonymous

Ohh, wow. Well goodnight-ish then..lol.

- anonymous

Haha, cheers, gn ;) Maybe I can blame my stupic mistakes on the time? :D

- anonymous

Lml..we both made silly mistakes, just bc we are human.

- anonymous

You hope I'm human.... :')

- anonymous

..oh no, im scared..I do hope you're human..lol.
