The law of cosines can be used to find the measure of an angle when the length of the three sides of a triangle are known. The law of cosines can be used to find the length of the side of a triangle when the lengths of the other two sides are known and the measure of the opposite angle is known. #trigonometry #lawofcosines
The four parts are three sides and one angle. So you either need 2 sides and an angle to solve for the remaining side or all three sides to solve for an angle. So if you know two angles (which lets you figure out the third so technically three angles) and a side you can't just use the law of cosines.

, Sal said that Law of Sines is 'ssin (a)/A = sin (b)/B = sin (c)/C (lower case letters are the angles and the upper case letters are the side opposite to the angle), in this article it says 'A/sin (a) = B/sin (b) = C/sin (c)'. So which one should I choose? The Law of Sines can be written either way!
