help- am i right here?

OpenStudy (eliesaab):

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

OpenStudy (iwanttogotostanford):

i believe it would be C am i correct here?

OpenStudy (iwanttogotostanford):

?

OpenStudy (peridot):

Just put c

OpenStudy (peridot):

And help me :)

OpenStudy (iwanttogotostanford):

i can't just put it i need to be right so if someone could help me find the answer that'd be good

OpenStudy (eliesaab):

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

OpenStudy (iwanttogotostanford):

ok can you show me?

OpenStudy (eliesaab):

Actually, I wanted to say d in the first place

OpenStudy (iwanttogotostanford):

so would it be D or C/ i think D but i want to be sure

OpenStudy (eliesaab):

Sorry

OpenStudy (eliesaab):

yes it is D

OpenStudy (iwanttogotostanford):

ok could you help me with another please???

OpenStudy (eliesaab):

Post it as different problem

OpenStudy (iwanttogotostanford):

ok
