The 3 little division "sums" that are the Sine and its brother ratios, Cosine and Tangent, given in any basic right-angled triangle, form the basis for the entire, vast field of Trigonometry and its uses, going far beyond simple Plane Geometry into such things as Harmonic Analysis (Sine functions of amplitude with respect to time), the Laws of Electricity (starting with the phase angle between Volts and Current in a.c. circuits, etc.), and so on.
The law of sines refers to a relationship between the sides and the angles of a triangle. Consequently, it is used in trigonometry and, to a lesser extent, in geometry. It is not really relevant in calculus or statistics.
Trigonometry mainly but also geometry, algebra.
Yes, the law of sines can be used in a right triangle. The law applies to any arbitrary triangle.

No, it does not.
In trigonometry sines and cosines are used to solve a mathematical problem. And sines and cosines are also used in meteorology in estimating the height of the clouds.

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.

The ACT asks questions about basic sines, cosines, and tangents. These questions can be answered without a calculator.
No, it does not.
There is no single law in trigonometry so the question makes no sense.
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.
Trigonometric ratios, by themselves, can only be used for right angled triangles. The law of cosines or the sine law can be used for any triangle.
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.
