Explicație pas cu pas:

40°+50°= 90°

24°38'+17°18'= 41° 56'

56°43'-21°18= 35° 25'

25°x4= 75°

108°+72°=180°

44°30'+16°20=60° 50'

70°52-20°12= 50° 40'

30°20'x3=90° 60' = 91°

90°-30°= 60°

57°35'+42°25'= 99° 60' = 100°

88°30'-43°50'= 87° 90' - 43°50' =44° 40'

90°/3= 30°

180°-50°= 130°

60°40°+50°50°= 110°90' = 111°30'     ( Probabil la 40 si al doilea 50 ai minute ,        nu grade 0 . Te rog sa-ti verifici enuntul din tema )

90°-32°30= 89°60' -32°30' = 57°30'

90°/4=88° 120' : 4 = 22°30'

Succes !!
