ok
there are two laws
cosine in sine
you should checkout the organic chemistry teacher or eddie woo if you want an explanation
The sine rule works when you know either two angles and one side (AAS) or two sides and a non-included angle (SSA)
a/Sin A = b/Sin B = c/ Sin C
The cosine rule is for when you know two sides and the included angle (SAS) or all three sides (SSS).
Ambiguous case too
ur right
No solution: If the side opposite the given angle is too short to reach the other side (like a swing that can't reach the base).
One solution: If the side opposite the angle is exactly as long as the height of the triangle or longer than the other known side.
Two solutions: If the opposite side is long enough to form two different triangles but not longer than the adjacent side.
