Answer 1

    
[tex]\text{Pentru a putea face scaderea, transformam unghiul de }~45^o~ astfel: \\ 45^o = 44^o\;60' = 44^o\;59'\;60'' \\ \\ 44^o\;59'\;60'' - \\ 24^o\;05'\;17'' \\ \text{-----------------} \\ 20^o\;54'\;43'' \\ \\ 20^o\;54'\;\;43'' + \\ 24^o\;55'\;\;12'' \\ \text{------------------} \\ 44^0\;109' \;55'' \\ \\ 44^0\;109' \;55'' = 44^0\;(60'+49')\;55'' = \boxed{45^o\;49'\;55'' }[/tex]
