Exercise: In figure below angle $$ and $$ were observed as $48{53}^{\text{'}}{12}^{\text{'}\text{'}}$ and $41{20}^{\text{'}}{35}^{\text{'}\text{'}},$ respectively. Control points A$,$ B$,$ and C have coordinates $($in meter$)$ of $x_A=5721\mathrm{.}25,Y_A=21802\mathrm{.}48,x_B=13542\mathrm{.}99,Y_B=22497\mathrm{.}95,x_C=20350\mathrm{.}09,$ and $Y_C=24861\mathrm{.}22.$ Calculate the coordinate of O using method of resection,
