In a triangle ABC, the sine rule is
Select the correct option:
Solution
Incorrect! Answer:
a/sin A = b/sin B = c/sin C
- The Law of Sines: Relates the sides of a triangle to the sines of its angles.
- Formula: sinAa=sinBb=sinCc=2R.
- Variable R: R represents the circumradius (radius of the circle passing through all three vertices).
- Usage: Excellent for solving triangles when you have a side-angle pair.
