Now we will use trigonometry to find a missing side or angle when given a side and an angle or when given two sides of a right triangle. We will need to develop three trigonometric ratios: sine, cosine, and tangent, which are abbreviated sin, cos, and tan. Look at the diagram at the right. If we use angle A as our reference angle, then we can ...

When the two sides and two angles are not matching pairs, the missing angle will need to be referenced using the information in the question to create matching pairs prior to using the sine rule. When finding missing angles, it is appropriate to use the reciprocal version of this rule, i.e. sin A a = sin B b = sin C c , and must use the inverse ...

two sides and a non-included angle, or, two angles and one side. The Sine Rule : Ambiguous case. The ambiguous case occurs when 2 sides and 1 angle of a triangle are given with the angle opposite the shorter side. There is no ambiguity if the given angle is obtuse or the side opposite the given angle is greater than the other side.
