A $125$ N sign is supported by two ropes. One rope pulls up and to the right ${}_1=28\mathrm{.}5$ above the horizontal with a tension $T_1,$ and the other rope pulls up and to the left ${}_2=52\mathrm{.}5$ above the horizontal with a tension $T_2,$ as shown in the figure. Find the tensions $T_1$ and $T_2.$

$T_1=$
