Alicia's Blog Topic Response

Okay so I am going to explain the 2nd topic.

Law of Sines
(sinA)/a = (sinB)/b = (sinC)/c

*The law of sines is used when you know pairs in non-right triangles

*Basically, all your doing is setting up a proportion


Law of Cosines
(opposite leg)^2 = (adjacent leg)^2 + (other adjacent leg)^2 -2(adjacent leg)(adjacent leg)cos(angle between)

*When doing law of cosines, you should always use an angle to orient yourself like SOHCAHTOA!
