From the following circuit I get that the equivalent impedance is Z = 25 - j150 which in polar form is a vector with magnitude 152.07 at an angle of -80.53 (when the angular frequency is 500) but the answer is a vector with magnitude 158 and angle of −71.57. Have I done something wrong or is the answer incorrect?
