Question

Which expression can be used to find the value of X?

Answer 1

Use the Law of Sines to find side b. 
b / sin(B) = a / sin(A) 
b / sin(32°) = 11 / sin(47°) 
b = (sin(32°) x 11) / sin(47°) <---- You would use this, so rewritten
11(sin(32))/sin(47) would be the expression, or answer B.)

BTW b = 7.970

Hope this helps!

Answer 2

the correct answer is C) 11(sin32°) / sin47°
