You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Consider a triangle where a = 5, b = 8, and c = 12. (Note that the triangle shown is not to scale.) Use the Law of Cosines to find the angle measure B in degrees.The reason is that using the cosine function eliminates any ambiguity: if the cosine is positive then the angle is acute, and if the cosine is negative then the angle is obtuse. This is in contrast to using the sine function; as we saw in Section 2.1, both an acute angle and its obtuse supplement have the same positive sine.This image demonstrates Unit 5 trigonometric functions homework 8 law of cosines answers.

In triangle ABC, Angle A = 40 degrees. x =. Find the indicated side x.Sep 16, 2022 · The reason is that using the cosine function eliminates any ambiguity: if the cosine is positive then the angle is acute, and if the cosine is negative then the angle is obtuse. This is in contrast to using the sine function; as we saw in Section 2.1, both an acute angle and its obtuse supplement have the same positive sine. The Law of Cosines is: c2 = a2 + b2 − 2ab ⋅ cosC. It is important to understand the proof: You know four facts from the picture: a = a1 + a2. b2 = a2 1 + h2. c2 = a2 2 + h2. cosC = a1 b. Once you verify for yourself that you agree with each of these facts, check algebraically that these next two facts must be true.This is a place to find notes, homework, and handouts from class.
