Law of Sines- We need the law of sines whenever we only have two angles and a side of a triangle (ASA AAS). We use it by putting the sin of the angle divided by the side of that same letter, and then making it equal to the sin of an angle (if we have it) over the side of the same letter (we must have at least one of these in order for this to work)

Area Formulas- The Area of an oblique triangle formula is A= .5* side *side times sin of angle. We must be given two sides and one angle of the triangle. The original area formula is A= .5 b *h. In this formula we substitute the sides in and the sin.
