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 !!
