8. Each figure below shows a circle on the coordinate Formulas: r = Vx2 + y2, sino =>, cos0 =x plane with an angle in standard position. For each figure, determine the sine of the angle and the cosine a. of the angle. sin 0 = cos 0 = ( - 4, -4V/3 b . (0. 24) sin 0 = cos 0 = C. Ae sin 0 = 14 -3 -2 -19 1 2 3 cos 0 =
