Problem $10\mathrm{.}040-$ Superposition when sources have different frequencies

Find the output current ${?}^{\text{'}}O$ in the circuit shown below using superposition, where $v_S=28cos(4)V.$ Given: $\frac{?}{O1}$ is the value of phasor $\frac{?}{O}$ when only $20$ V source is on and $I_0$ is its value with $v_S(t)$ on only. Please report your answer so the magnitude is positive and all angles are in the range of negative $180$ degrees to positive $180$ degrees.

The value of $101=q,$ A$.$

The value of $102=4!A.$

The output current $+9)$ A
