Law of sines - Wikipedia
https://en.wikipedia.org/wiki/Law_of_sines
WEBThe law of sines is one of two trigonometric equations commonly applied to find lengths and angles in scalene triangles, with the other being the law of cosines. The law of sines can be generalized to higher dimensions on surfaces with constant curvature.

The Law of Sines - Math is Fun
https://www.mathsisfun.com/algebra/trig-sine-law.html
WEBLaw of Sines: a/sin A = b/sin B = c/sin C. Put in the values we know: a/sin A = 7/sin (35°) = c/sin (105°) Ignore a/sin A (not useful to us): 7/sin (35°) = c/sin (105°) Now we use our algebra skills to rearrange and solve: Swap sides: c/sin (105°) = 7/sin (35°) Multiply both sides by sin (105°): c = ( 7 / sin (35°) ) × sin (105°)

WEBThe Law of Sines just tells us that the ratio between the sine of an angle, and the side opposite to it, is going to be constant for any of the angles in a triangle. So for example, for this triangle right over here. This is a 30 degree angle, This is a 45 degree angle. They have to add up to 180.

WEBLaw of Sines. In trigonometry, the Law of Sines relates the sides and angles of triangles. Given the triangle below, where A, B, and C are the angle measures of the triangle, and a, b, and c are its sides, the Law of Sines states: Generally, the format on the left is used to find an unknown side, while the format on the right is used to find an ...

WEBThe Law of Sine tells us the ratio between the sine of each of these angles and the length of the opposite side is constant. So sine of lower case a over capital A is the same as lower case b over capital B, which is going to be the same as lower case c over capital C. Let's see if we can leverage that somehow right over here.
