Word problem of oblique triangle using law of sines?

What situation would you be FORCED to use law of cosines as opposed to law of sines?
When none of the angles are known, and using Pythagoras, the triangle is known not to be right angled.
How do you use the law of sines?
The Law of Sines can be used to find unknown parts (a side or angle) of a triangle. For example if you know 2 angles and a side, or if you know 2 sides and 1 angle (depending on how they are oriented). Visit the Maths Is Fun site (link posted below) for a more graphical explanation.
When can you use the sine law?
The tricky part of the law of sines is knowing when you are able to use it. Whether you can use the law of Sine's or not depends on what information you have or were given. In some cases the information you were given could make two different triangles. There are three times when you can use the law of sines. One example of when you can use it is when you have the length of a side and the measures of both the angles that that side is adjacent to. This is called angle side angle or asa for short. Another time when you can use the law of sines is when you are given the measures of two angles and a side that is outside the angles. This is called aas. Finally the last case where you can use the law of sines is when you have two side lengths and the measure of an angle. Math teachers refer to this one as ssa, I remember that this one is special. If you are given the measure of an angle and two sides you could have two different triangles.
What is Law of the sine?
The law of sines is a statement about arbitrary triangles in the plane.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle. Put more simply, it means that if you take the sine of an angle, the value will be equal to the length of the opposite side divided by the length of the hypotenuse. The practical application of this is when you know the length of only one side and the measure of one angle (other than the right angle) you can determine the other sides and the remaining angle.The law of sines states that in any right triangle, the ratio of the opposite side length to the length of the hypotenuse (relative to an acute angle) is always relative to the size of the angle. Put more simply, it means that if you take the sin of an angle, the value will be equal to the length of the opposite side divided by the length of the hypotenuse. The practical application of this is when you know the length of only one side and the measure of one angle
Definition of law of sines?
The law of sines is used to find missing values in triangles. The formula is a/sinA=b/sinB=c/sinC. The idea behind the equation is that the larger an angle is the larger the side across from it will be and the smaller the angle the smaller the side across from it will be. Once you have set up your equation you can easily solve your equation with some simple algebra and a calculator.
Does the transitive property apply for the law of sines?
No, it does not.
Why Lami's theorem cannot be used for 4 concurrent forces?
Because, this theorem comes from the law of sines which is completely a triangle law and the law of sines can not be applied on other polygons.
When do you use law of sines and law of cos sines?
Use Law of Sines if you know:Two angle measures and any side length orTwo side lengths and a non-included angle measure.Use Law of Cosines if you know:Two side lengths and the included angle measure orThree side lengths.
Can ASA work with the law of sines?
Yes. If you have two angles, by implication, you have all three. You therefore have a pair of opposite angle and side so that the law of sines can be applied.
When do you use law of sine?
There are several cases when you would want to use the law of sines. When you have angle angle side, angle side angle, or angle side side you would use the law of sines.
When the formula equation is correctly balanced the coefficient?
When the formula equation is correctly balanced, the coefficients represent the relative number of moles of each substance involved in the reaction. This ensures that the number of atoms on each side of the equation is the same, satisfying the law of conservation of mass.
Which of newtons laws represents the equation Fma?
Newton's 2nd law is F=ma.
What feature of a chemical equation represents the law of conservation of matter?
The balancing of the number of atoms of each element on both sides of the equation represents the law of conservation of matter in a chemical equation. This ensures that mass is conserved in a chemical reaction.
Proof of lami's theorm?
Proof comes directly from the law of sines.
