Hint: the law of sines says

a/sin(A) = b/sin(B) = c/sin(C)

in this case, you can boil that down to

b/sin(B) = c/sin(C)

anonymous · Answer

I just dont know where to put all the numbers into the equation

jim_thompson5910 · Answer

in this case

b = unknown
B = 121
c = 25
C = unknown

anonymous · Answer

sin C= 25 sin 121, so 21.429?

well you can't solve, but that's not what they want

jim_thompson5910 · Answer

they want to know what you need to solve

jim_thompson5910 · Answer

and that would be either side b or angle C

jim_thompson5910 · Answer

if you had that info (either piece), then you can then use it to find the other pieces of info
