Answer 1

Resposta:

al 28° 12'+ 52°40'

28° + 12' + 52° + 40'

28° + 52° + 12' + 40'

(28 + 52)° + (12 + 40)'

80° + 52'

80° 52'

b)25° 40' + 16°50’

25° + 40' + 16° + 50'

25° + 16° + 40' + 50'

(25 + 16)° + (40 + 50)'

41° + 90'

41° + 60' + 30'

41° + 1° + 30'

(41 + 1)° + 30'

42° + 30'

42° 30'
