This week in Pre Calc, we learned about sine Law and how we can apply it to find the side and angle of a triangle. In the picture below, the degree of the angles are also the same as the sides that they are pointing to. (Example side ‘a’ is across from angle ‘A’)

The first formula is used to find the angle if the triangle (theta) and the second formula is used to find the side of an angle.

Example:
