What are the answers to law of cosines in A plus?
The law of cosines can be written in one form as: c2 = a2 + b2 - 2abCos C. Without 3 of the 4 variables being given, there is no way to answer this question.
What is a form of the law of cosines?
The question asks about the "following". In such circumstances would it be too much to expect that you make sure that there is something that is following?
What problem types can always be solved by using the law of cosines or sines?
The law of cosines and sines can always be used to solve problems involving triangles, specifically when dealing with non-right triangles. The law of cosines is applicable for finding a side or angle when you know either two sides and the included angle or all three sides. The law of sines can be used when you have two angles and one side (AAS or ASA) or two sides and a non-included angle (SSA). Both laws are essential in solving triangle problems in various applications, including navigation and physics.
Solving oblique triangle?
To solve an oblique triangle (a triangle without a right angle), you can use the Law of Sines or the Law of Cosines, depending on the information given. If you have two angles and one side (AAS or ASA), you can apply the Law of Sines to find the unknown sides. If you have two sides and the included angle (SAS) or all three sides (SSS), the Law of Cosines is appropriate. By using these laws, you can find the remaining sides and angles of the triangle.
Law of cosines with a right angle?
The law of cosines with a right angle is just the pythagorean theorem. The cosine of 90 degrees is 0. That is why the hypotenuse squared is equal to the sum of both of the legs squared

Can you use the Law of Cosines to solve a triangle when you are given two side lengths and the included angle measure?
Yes, absolutely
Is this statement true or falseYou can use the Law of Cosines to solve a triangle when you are given the lengths of the three sides and no angle measures?
true
Who discovered the law of cosines?
A caveman from 10,000 BCal-Kashi was the 1st to provide an explicit statement of the law of cosines in a form suitable for triangulation

The law of cosines and sines can be used to solve various types of problems involving triangles, particularly in non-right triangles. The law of cosines is useful for finding the lengths of sides or angles when two sides and the included angle are known, or when all three sides are known. The law of sines is effective for solving problems involving two angles and one side (AAS or ASA) or two sides and a non-included angle (SSA). Both laws are commonly applied in navigation, physics, engineering, and architecture where triangulation is necessary.
When you have a right angle what does the law of cosines reduce to?
cosine = adjacent/hypotenuse
Can the law of cosines be applied to right and non-right triangles?
Yes
