Answer 1

resposta:

a) Resolvendo:

12°13'14'' + 30°38'40'' = (12+30)°(13+38)'(14+40)''

12°13'14'' + 30°38'40'' = 42°51'54''

b) Resolvendo:

81°40'15'' + 45°12'55'' = (81 + 45)°(40 + 12)'(15 + 55)''

81°40'15'' + 45°12'55'' = 126°52'70'' = 126°53'10''

c) Resolvendo:

46°40'18'' - 12°30'10'' = (46 - 12)°(40 - 30)'(18 - 10)''

46°40'18'' - 12°30'10'' = 34°10'8''

d) Resolvendo:

90° - 73°43'45'' = (90 - 73)°(0 - 43)'(0 - 45)''

90° - 73°43'45'' = 16°16'15''

e) Resolvendo:

5 × 25°45’ = (5 × 25)°(5 × 45)’

5 × 25°45’ = 125°225’ = 128°45'

f) Resolvendo:

3 × 56°14’19’’ = (3 × 56)°(3 × 14)’(3 × 19)’’

3 × 56°14’19’’ = 168°42’57’’

g) Resolvendo:

75° ÷ 2 = 37,5° = 37°30'

h) Resolvendo:

59°40’33’’ ÷ 3 = (59 ÷ 3)°(40 ÷ 3)'(33 ÷ 3)''

59°40’33’’ ÷ 3 = 19,67°13,33'11''

59°40’33’’ ÷ 3 = 19°(40+13)'(20+11)''

59°40’33’’ ÷ 3 = 19°53'31''
