Correct Answer:
@.
Explanation:
The value of sin 30° is 1/2. This can be determined using a standard 30-60-90 right triangle, where the side opposite the 30° angle is exactly half the length of the hypotenuse. In the unit circle, the sine of an angle corresponds to the y-coordinate of the point on the circle, and for 30° (or π/6 radians), that coordinate is 0.5.
