Introduction:

To solve a triangle is to find the lengths of each of its sides and all its angles. The sine rule
is used when we are given either a) two angles and one side, or b) two sides and a non-included
angle. The cosine rule is used when we are given either a) three sides or b) two sides and the
included angle.

Given: Triangles with some measurements.

To find: Remaining sides and angles.
