Question

Check my answer? Law of sines.

Answer 1

Angle B is obviously 55 degrees.
Using the law of sines, I got 142.95 units for the length of side a and 61.9 for side c.
However, mathwarehouse says I'm wrong. :/ Did I do something wrong? I know there is some ambiguous thing or something with the law of sines... I'd really appreciate some help!

Answer 3

Sorry! here

Answer 4

@Evoker still there? :)

Answer 5

Ok looking now

Answer 6

142.95 for a looks right

Answer 7

212.04 for c though

Answer 8

I used law of sines for that result, nothing special

Answer 9

\[\frac{ 175 }{ \sin55 } = \frac{ c }{ \sin83 }\]

Answer 10

Like so?

Answer 11

yes that's right so c=sin(83)*175/sin(55)

Answer 12

b / sin(B) = c / sin (C)
175 / sin(55) = c / sin (83)
c = sin(83) * 175 / sin(55)
c = .9925*175/.81915
c = 173.6875 / .81915
c = 212.0338155405
