# 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.

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.
