Question

Which of the following equations correctly represents the law of sines?A. a=!c sin Asin Cc sin Csin Aa sin Asin COB.a =O C. a=O D. a =a sin Csin A

Answer 1

The Solution:

We are required to determine the Law of Sine from the given options.

The Law of Sine is:

`(a)/(\sin A)=(c)/(\sin C)`

Cross multiply:

`a\sin C=c\sin A`

Divide both sides by sinC.

`a=(c\sin A)/(\sin C)`

Therefore, the correct answer is [option A ]
