Answer 1

Răspuns:

Explicație pas cu pas:

a) 23°14' +10°33' = 33°47'

b) 19°39'-7°21' = 12°18'

e) 34°18' +18°52' = 52°70' = 53°10'

f) 71°23' - 63°29' = 70°83' - 63°29' = 7°54'

c) (41°2')· 3 = 123°6'

g) 5·(21°30') = 105°150' = 107°30'

d) 19°39' :3 = 6° + (99':3) = 6°+33' = 6°33'

h)  (28°48'):6 = 4°+(288':6) = 4°+48' = 4°48'

28°-24° = 4° = 4·60 = 240'

240'+48' = 288'

1° = 60'  ; 1' = 60''
