Prove the law of sines
WebbLaw of Sines Formula The law of sines formula allows us to set up a proportion of opposite side/angles (ok, well actually you're taking the sine of an angle and its opposite side). For instance, let's look at Diagram 1. One side of the proportion has side A and the sine of its opposite angle . WebbWhen you write and solve the law of sines, you end up with sinC=0.32 or something. You type sin^-1(0.32) in your calculator and you are given an acute angle. Actually there are …

WebbThe Law of Sines is a relationship among the angles and sides of a triangle The ratio of the sine of any of the interior angles to the length of the side opposite that angle is the same … WebbThe law of cosines relates the length of each side of a triangle, function of the other sides and the angle between them. If the angle is 90° (π/2), the law of cosines becomes Pythagoras’s theorem. In a scalene triangle, knowing the length of two sides and the angle between them, we can calculate the length of the third side.
