Use
\[
\frac a{\sin(A)}=\frac b{\sin(B)}
\]
OpenStudy (iwanttogotostanford):
@eliesaab
OpenStudy (eliesaab):
First you get sin(A)=.8625
OpenStudy (eliesaab):
This gives A= 59.6
OpenStudy (eliesaab):
The answer is c and d. Try to get more information to decide between c and d

Use the law of cosine now to find c=3.4
OpenStudy (eliesaab):
also c=17.6
OpenStudy (iwanttogotostanford):
I believe it will be D then what do you think?
OpenStudy (iwanttogotostanford):
so it would be this: A = 59.6°, C = 71.4°, c = 11.1; A = 120.4°, C = 10.6°, c = 11.1
OpenStudy (eliesaab):
May be it is D. Let us do some more computations

ok can you show me?
OpenStudy (eliesaab):
Actually, I wanted to say d in the first place
OpenStudy (iwanttogotostanford):

OpenStudy (eliesaab):
Sorry
OpenStudy (eliesaab):
