❤La exercitiul 5 am nevoie de calcule❤ ❤unul sub altul mai usor pe o fișă da va❤ rog repedee!!!!❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤​

Answer 1

34° + 56° = 90°

75° - 28° = 47°

19°·8 = 152°

154° : 7 = 22°

27°18' + 56°24' = 83°42'

5°38' + 8°53' = 13°91' = 14°31'

75° - 28°53' = 74°60' - 28°53' = 46°7'

27°45'·5 = 135°225' = 138°45'

75° : 4 = 72°180' : 4 = 18°45'

122°50' : 5 = 120°170' : 5 = 24° 34'

Answer 2

Explicație pas cu pas:

1 grad = 60 minute !!

a) 34° + 56° = 90°

b ) 75° - 28° = 47°

c) 19° * 8 = 152°

d) 154° : 7 = 22°

e) 27°18' + 56°24' =

83°42'

f) 5°38' + 8°53' =

13°91' = 14°31'

g) 75° - 28°53' =

74°60' - 28°53' = 46°7'

h) 27°45' × 5 =

135°225' = 138°45'

i ) 75° : 4 =

75 : 4 = 18° rest 3° = 3° × 60' = 180'

180' : 4 = 45'

18°45'

j) 122°50' : 5 =

122 : 5 = 24° rest 2° = 2° × 60' = 120'

120' + 50' = 170'

170' : 5 = 34'

24°34'
