Laws of sines and cosines review (article)
The law of sines works only if you know an angle, a side opposite it, and some other piece of information. If you know two sides and the angle between them, the law of sines won't help you. In any other case, you need the law of cosines. Comment Button navigates to signup page (3 votes)
PDF 7.1 7.2 Law of Sines Practice Worksheet
The LAW OF SINES is a powerful triangle tool which is used to find missing sides or angles of ANY triangle. By matching up angles with their opposite sides, the equation is:
Law of sines: solving for an angle
Multiplying both sides times 40, you're going to get, let's see. 40 divided by 30 is 4/3. 4/3 sine of 40 degrees is equal to sine of theta, is equal to sine of theta. Now to solve for theta, we just need to take the inverse sine of both sides. So inverse sine of 4 over 3 sine of 40 degrees. Put some parentheses here, is equal to theta.
