Which of the following explains why cos60 = sin30 using the unit circle?
a.) 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.
b.) 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 x (sin) distance of a 30° angle is the same as the y (cos) distance of a 60° angle.
c.) the ratios describe different sides of the same 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.
d.) the ratios describe different sides of the same right triangle. on a unit circle, the x (sin) distance of a 30° angle is the same as the y (cos) distance of a 60° angle.
