The given equation is,
[tex]V=60\sin \theta[/tex]Where,
[tex]\begin{gathered} V_0=Voltage=60 \\ \theta=angle \\ V_{\text{rms}}=\text{?} \end{gathered}[/tex]The formula for V(rms) is
[tex]V_{\text{rms}}=\frac{V}{\sqrt[]{2}}[/tex]Evaluate V(rms)
[tex]V_{\text{rms}}=\frac{60}{\sqrt[]{2}}=42.4264\approx42.42[/tex]Hence, the answer is 42.42 (Option D).
