Using source transformation, find $i$ in the circuit given in the figure. Take $i_s = 19cos(70t + 30^\circ) A$.
The current $i = I_m cos(70t + \theta)$ A, where
$I_m = $ ______ A (Calculate to 2 decimal places)
$\theta = $ ______ deg (Calculate to 2 decimal places)
Please report your answer so the magnitude is positive, and all angles are in the range of negative 180 degrees to positive 180 degrees.
