(Section 6.1: The Law of Sines) 6.01 CHAPTER 6: ADDITIONAL TOPICS IN TRIG SECTION 6.1: THE LAW OF SINES PART A: THE SETUP AND THE LAW The Law of Sines and the Law of Cosines will allow us to analyze and solve oblique (i.e., non-right) triangles, as well as the right triangles we have been used to dealing with.
ANSWER: This triangle does not exist. To summarize the Ambiguous Case: Unlike the Ambiguous Case for the Law of Sines with all of its possible situations, the Ambiguous Case for the Law of Cosines leaves the decision making on the number of triangles (or solutions) to the quadratic equation.
Learn the laws of sines and cosines from certified online trigonometry tutor It states that “When we divide side a by the sine of angle A, it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C”. It can be used to – Calculate the unknown sides (Triangulation)

Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse, while cos(θ) is the ratio of the adjacent side to the hypotenuse. No matter the size of the triangle, the values of sin(θ) and cos(θ ...

Law of Cosines in "words": "The square of one side of the triangle is equal to the sum of the squares of the other two sides minus twice the product of the other two sides and the cosine of the angle between them. " Notice that the Law of Cosines works with only ONE angle and three sides in each formula.

11.8 Sine and Cosine Laws Right angle trigonometry is generally limited to triangles that contain a right angle. It is possible to use trigonometry with non-right triangles using two laws: the sine law and the cosine law. The Law of Sines. The sine law is a ratio of sines and opposite sides. The law takes the following form:
The law is still on the British statute books, and a version of it is used in the United States, where the law was regarded as such an important guarantee of liberty that Article 1 of the Constitution declares that "Habeas Corpus shall not be suspended except in cases of rebellion or invasion".
