A) 4.97 °
B) 5.03 °
C) 10.14 °
D) 29.86 °

The angle theta ( ∠θ ) in an RL circuit can be found using the arctan function of the inductive reactance (XL) over the resistance (R), i.e., θ = arctan(XL/R). Plugging in the given values, θ = arctan(155/270). Calculating this gives an angle of approximately 29.86 degrees.
