1/2 complemento = 22°37´38´´ então o complemento será
2.(22°37´38´´) = 44°74´76´´ = 48° + (60 + 14)´ + (60 + 16)´´
= 48° + 1° + 18 + 1´ + 16´´ = 45° + 15´ + 16´´ = 45°15´16´´ 

 = 90° - 45°15´16´´
 = 89°59´60´´ - 45°15´18´´ = (89 - 45)°(59 - 15)´(60 - 16)´´ =
 = 40° 67°

A)18° = 90º-18º= 72º   
                                  
   
B)56° = 90º-56º= 34º

C)31° 30' =
90º-31° 30' = 89º60'-31° 30'= 58º29'
             

D)67°40' = 90º-67°40'= 89º60'-67°40'= 22º20'
