Do you know law of sines?
anonymous
  • anonymous
i couldn't do it on this
anonymous
  • anonymous
yes, you can to find the angle x.

x=sin-1(.0087679 then what do i do
anonymous
  • 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
  • anonymous
Looks to me like\[c^{2} = a^{2} + b^{2} - 2bc CosA\]
anonymous
  • anonymous
Correct me if I'm wrong; please - Is that triangle a right angle??
anonymous
  • anonymous
i have no clue what do u think brittini
anonymous
  • anonymous
nd no its not a right angle
anonymous
  • anonymous
Law of sines is not only for right triangles.
anonymous
  • anonymous
You cant use law of cosines, and I think if you were to try @ScottB05 's setup is incorrect.
anonymous
  • anonymous
Ok, you still cant use the law of cosines.
anonymous
  • anonymous
but how do i start in this problem
anonymous
  • anonymous
I would say since the angles in a triangle must add to 180 degrees. Find your missing angle.
anonymous
  • anonymous
|dw:1355439236917:dw| Again - Please tell me if I'm going about this the wrong way?
anonymous
  • anonymous
Oh.... Right ignore me completely you made a mistake apparently - I'm so stupid sometimes -.-
anonymous
  • anonymous
im confused
anonymous
  • anonymous
I still disagree with @ScottB05
anonymous
  • anonymous
With good reason, I said I'm wrong already xD
anonymous
  • anonymous
Oh, okay. :p
anonymous
  • anonymous
now u think its solved by the law of cosines
anonymous
  • anonymous
No, I think law of sines
anonymous
  • anonymous
okay srry but lets start from the beginning because i got messed up with all this srry brittini
anonymous
  • anonymous
No prob.
anonymous
  • anonymous
thnxs k

So, since you know two angles..can you find the third one? Hint: all angles in a triangle add up to 180 degrees
anonymous
  • anonymous
63 degrees
anonymous
  • anonymous
Great, so now your triangle looks like: |dw:1355440610624:dw|
anonymous
  • anonymous
:-( can u show me the equation to help solve it
anonymous
  • anonymous
You can use law of cosines.

x=1924.7 its so off
anonymous
  • anonymous
what did u get brittni
anonymous
  • anonymous
@Brittni0605 You've done what I've done way up My answer to that equasion was x = 26.9
anonymous
  • anonymous
i know but i did something wrong
anonymous
  • anonymous
wait actually u did the wrong problem this is the right one |dw:1355443147072:dw|
anonymous
  • anonymous
can u try to solve it and see what u get
anonymous
  • anonymous
|dw:1355443262333:dw|
anonymous
  • anonymous
thats much better thnxs i really understood my mistake
anonymous
  • anonymous
I may still be wrong but I believe this to be correct. Right until proven wrong =)
anonymous
  • anonymous
i think its the right answer
anonymous
  • anonymous
oops, sorry guys, I was eating.
anonymous
  • anonymous
hhh its alright so i think we got the right answer
anonymous
  • anonymous
I'd be happier if @Brittni0605 double checked my answer - I was wrong before :)
anonymous
  • anonymous
what do u think brittni
anonymous
  • anonymous
Hm, this is interesting. The picture must be drawn incorrectly, two angles are equal so it has to be an isosceles triangle.
anonymous
  • anonymous
its not exactly the same as the assignment but im new in this drawing thing
anonymous
  • anonymous
|dw:1355444759541:dw|
anonymous
  • anonymous
maybe that's better..
anonymous
  • anonymous
yup way better :p
anonymous
  • anonymous
I agree with thinking x= 9.56
anonymous
  • anonymous
thnxs people i will close the question and i really appreciate ur help
anonymous
  • anonymous
Yep, np.
anonymous
  • anonymous
|dw:1355445651964:dw|Hmm... Wait actually... Haha I just saw something cause u drew it like that
anonymous
  • anonymous
Hmm..
anonymous
  • anonymous
Umm, cosine would be adjacent over hypotenuse, not hypotenuse over adjacent.
anonymous
  • anonymous
|dw:1355446061993:dw|Of course :L
anonymous
  • anonymous
Hmm, and for the original triangle..xsin54 = 8sin63, x= 8.81
anonymous
  • anonymous
So looks like we found a solution, x = 8.81; after about 2 hours? :)
anonymous
  • anonymous
Lol, phew, I feel so dumb.
anonymous
  • anonymous
hhh really its hilarious so THE ANSWER IS 8.81 for sure :p
anonymous
  • anonymous
Yes, I agree. Sigh.
anonymous
  • anonymous
Well in Scotland it's 1.10 am; I can sleep happy knowing it's solved! :)
anonymous
  • anonymous
Ohh, wow. Well goodnight-ish then..lol.
anonymous
  • anonymous
Haha, cheers, gn ;) Maybe I can blame my stupic mistakes on the time? :D
anonymous
  • anonymous
Lml..we both made silly mistakes, just bc we are human.
anonymous
  • anonymous
You hope I'm human.... :')
anonymous
  • anonymous
..oh no, im scared..I do hope you're human..lol.
