ACT Math Prep Trigonometry: The Law of Sines
In this ACT Math prep video, we cover The Law of Sines. The rules of SOH-CAH-TOA and hypotenuse, opposite and adjacent sides only apply to right triangles. When we don't have a right triangle, other formulas sometimes need to be used to find sides and angles. One of those formulas is The Law of Sines.
A brief overview of the formula is given, and then two different methods using the formula are used to solve the problem.
