Given the circuit in the figure and its values, determine:

a$.$l$\_($aA$)=$

b$.$I$\_($bB$)=$

c$.$I$\_($cC$)=$

d$.$V$\_($CA$)=$

e$.$l$\_($AB$)=$

f$.$l$\_($BC$)=$

Line voltages $($in Vrms$)$:

Va $=394\backslash$angle $-50\backslash$deg

Vb $=394\backslash$angle $-70\backslash$deg

Vc $=394\backslash$angle $170\backslash$deg

Impedances $($in ohms$)$:

ZL$1=4\mathrm{.}2+$j$6\mathrm{.}7$

Z$1=17\mathrm{.}5+$j$26\mathrm{.}5$

Z$2=25\mathrm{.}5+$j$28\mathrm{.}5$

Z$3=19\mathrm{.}5+$j$28\mathrm{.}5$
