Answer 1

Răspuns:

Explicație pas cu pas:

a) 37°15'36" + 43°41'15" = 80°56'51''

15°49'53" + 28°41'48” = 43°90'101'' = 43°91'41'' = 44°31'41''

3·24°30' + 4·15°15' = 72°90' + 60°60' = 132°150' = 134°30'

72°24':6 + 36°45':9 = 12°4' + 4°5' = 16°9'

b)  47°39' - 26°27' = 21°12''

90° - 43°30'45" = 89°59'60'' - 43°30'45'' = 46°29'15''

180° - 104°41'59" = 179°59'60'' - 104°41'59'' = 75°18'1''

4·25°30' - 3·14°20' = 100°120' - 42°60' = 58°60' = 59°
