Question

Which of the following equations correctly represents the law of sines?

A. b= b sin C/sin C
B. b= c sin C/sin B
C. b= c sin B/sin C
D. b= b sin B/sin C

Answer 1

The Law of Sines may be written as
b/sin(B) = c/sin(C)

Multiply each side by sin(B).
b = (c*sin(B))/sin(C)

The correct answer is C.

Answer: C. (c*sin B)/sin C
