Given the network in Fig. P$8\mathrm{.}52,$ determine the magnitude of the $V_o$ phasor if $V_s=23V,R1=7,$ and $R2=4.$

Note: The Vo phasor will also have a phase angle, but this problem is only asking for the magnitude of the phasor, not the phase angle.

Provide your answer in Volts to the nearest tenth of a Volt

Do not include any units in your answer

Ex$.$ If the magnitude is $5\mathrm{.}12$ V $,$ your submitted answer would be $5\mathrm{.}1$
