i dont understand it

OpenStudy (anonymous):

Ok... so this is complicated but its a bit simple to understand depending on how you go about solving it ok?

ive tried sin and cosin

OpenStudy (anonymous):

The only thing is that im going to assume there isnt another diagram to compare it to?

nope there is not

hartnn (hartnn):

use sine rule $$\huge \dfrac{\sin B}{b}=\dfrac{\sin C}{c}$$

OpenStudy (anonymous):

He said he tried that hartnn

hartnn (hartnn):

B= 54.33 C=29.16 c=3 then try again :)

ive tried that the answer i got was 4.49

OpenStudy (anonymous):

Hartnn the 54.33 was already given >_>

hartnn (hartnn):

3 sin 54.33/ sin 29.16 = 3.089

OpenStudy (anonymous):

Ladie..not that i dont mind...but why follow me? im a freshman >_>

hartnn (hartnn):

yeah, can you verify the Question or choices ?

they came right from the website

OpenStudy (anonymous):

The closest answer to 3.089 is C...

OpenStudy (anonymous):
