In the same system shown in Question $2$ determine the tension forces in wires CA and CB $($FCA and FCB $),$ always considering that cable CB is subjected to a tension force that is four times higher than the tension force for cable CA $($for angles a and $b$ use the values calculated in question $2).$ The system is in static equilibrium.

FCA$=20\mathrm{.}27N,FCB=81\mathrm{.}08N$

FCA$=42\mathrm{.}27N,FCB=161\mathrm{.}08N$

FCA$=24\mathrm{.}17N,FCB=96.\mathrm{.}68N$

FCA$=12\mathrm{.}37N,FCB=49\mathrm{.}48N$

FCA$=22\mathrm{.}27N,FCB=89\mathrm{.}08N$
