Use the properties of the sine and cosine to solve the problem.Assume cos(0.67) = 0.78Find sin(0.67), cos(-0.67), and cos(0.67 - 8?).
A. sin(0.67) = 0.63 cos(-0.67) = 0.78 cos(0.67 - 8?) = 0.78 B. sin(0.67) = 0.22 cos(-0.67) = -0.78 cos(0.67 - 8?) = -0.78 C. sin(0.67) = 0.63 cos(-0.67) = -0.78 cos(0.67 - 8?) = -0.78 D. sin(0.67) = -0.63 cos(-0.67) = 0.22 cos(0.67 - 8?) = 0.78
