So for example, …
SpletTo use the Law of Sines (called the Sine Rule in some places), you must have the following information. The known values of an angle and its opposite side (one pair). The known value of either an angle OR its opposite side (half of one pair). That is dense information. A lot of experience (practice) is required for it to make sense.
