This week in Precalculus 11, we learned about the sine law.
Sine law is used to find side lengths or angles in a triangle. To use sine law and solve a missing value, we must be given 2 side lengths and one non-contained angle, or 2 angles and a side length. A non-contained angle in a triangle is an angle that is not in between two side lengths.
This is the formula for sine law.
