Explanation / Answer

B) tan(phi) = XL/R

tan(65) = XL/R

2.144 = XL/R

==> XL = 2.144*R

impedance of the ckt, z = sqrt(R^2 + XL^2)

= sqrt(R^2 + (2.144*R)^2)

= 2.366*R

now Apply, I = V/z

z = V/I

2.366*R = 120/5.5

R = 21.8/2.366

R = 9.22 ohms

XL = 2.144*R

2*pi*f*L = 2.144*9.22

L = 2.144*9.22/(2*pi*60)

= 0.0524

= 52.4 mH

L = 52.4 mH <<<<<<<<---------Answer

R = 9.22 ohm<<<<<<<<<---------Answer
