Please help me understand how my professor solved this and plugged in the values

Problem 6: Given the following circuit determine (a) the reactance and (b) the RMS voltage across the inductor. Assume the the inductor value is Lo := 11.2 . H and the AC source has a frequency of f, =33.4 . Hz with an RMS current of Ing :=22.9 . A. X1 := 2 . 7 . f1 . (Lo) = (2.35 - 103) n 0000 L UL Vrs =XL.ITS= (5.382 . 101 ) V
