Which of the following explains why cos 60° - sin 30° using the unit circle?
the side opposite a 30° angle is the same as the side adjacent to a 60° angle in a right triangle. on a unit circle, the y (sin)
distance of a 30° angle is the same as the x (cos) distance of a 60° angle

the ratios describe different sides of the same right triangle. on a unit circle, the y (sin) distance of a 30° angle is the
