The correct answer is B. in fact we can say this without even do the work as each response to Cos(α) = Sin(90 - α) due to the way in which the Sin and the Cos of the wave to behave. However, we can also say this through the use of the math assessment. Sin(Y) = Cos(90 - Y)Sin(50) = Cos(90 - 50).766 = Cos(40).766 = .766This should that are exactly the same.
