EASY MULTIPLE CHOICE!!!
For which unknowns is the Law of Sines not used?
2 angles and a side opposite
2 sides and an angle opposite
an angle and two sides opposite
A sine law is used to relate the sides of a triangle to its angles. Thus, it is only applicable if the 2 sides and an angle is known, also when 2 angles and one side. This leaves that an angle and two opposite sides cannot be used for sine law.
