To find the value of t in a triangle, you can generally use either the Law of Sines or the Law of Cosines, depending on the information you have.
1. Law of Sines: This can be used when you know two angles and one side (AAS or ASA) or two sides and a non-included angle (SSA). It states that the ratios of the sides of a triangle to the sines of their opposite angles are equal.
2. Law of Cosines: This is applicable when you know two sides and the included angle (SAS) or all three sides (SSS). It relates the lengths of the sides of a triangle to the cosine of one of its angles.
3. Pythagorean Theorem: This is specifically used for right triangles and relates the lengths of the sides as (a^2 + b^2 = c^2).
If the context provides specific angles or sides, you can determine which law to apply.
