Final answer:
The Law of Sines for a triangle is represented by the equation C) sin A/a = sin B/b = sin C/c, which expresses the relationship between the lengths of sides and sine of the opposite angles.
Step-by-step explanation:
The equation that represents the Law of Sines for ΔABC is C) sin A/a = sin B/b = sin C/c. This formula is used to find unknown angles or sides in any triangle, not just right-angled triangles. The Law of Sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides and angles in a triangle.
