options: Prove the Laws of Sines and Cosines and use them to solve problems.

Derive the formula A = 1/2 ab sin(C) for the area of a triangle by drawing an auxiliary line from a vertex perpendicular to the opposite side.

Understand and apply the Law of Sines and the Law of Cosines to find unknown measurements in right and non-right triangles (e.g., surveying problems, resultant forces).
problem_activity: Use the Law of Sines to find the lengths
$$b$$
and
$$c$$
in the triangle below. Round answers to the nearest tenth as necessary.
