✅ A) 12°13’14’’ + 30°38’40’’ = 12°13'14'' + 30°38'40'' =
(12+30)°(13+38)'(14+40)''
12°13'14'' + 30°38'40'' =
42°51'54''
✅ b) 81°40’15’’ + 45°12’55’’ = 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) 46°40’18’’ – 12°30’10’’ = 46°40'18'' - 12°30'10'' =
(46 - 12)°(40 - 30)'(18 - 10)''
46°40'18'' - 12°30'10'' = 34°10'8''
✅ d) 90° – 73°43’45’’ = 90° - 73°43'45'' =
(90 - 73)°(0 - 43)'(0 - 45)''
90° - 73°43'45'' = 16°16'15''
✅ e) 5 × 25°45’= 5 × 25°45’ =
(5 × 25)°(5 × 45)’
5 × 25°45’ = 125°225’ = 128°45'
✅ f) 3 × 56°14’19’’= 3 × 56°14’19’’ =
(3 × 56)°(3 × 14)’(3 × 19)’’
3 × 56°14’19’’ = 168°42’57’’
✅ g) 75° ÷ 2= 75° ÷ 2 = 37,5° = 37°30'
75° ÷ 2 = 37,5° = 37°30'
✅ h) 59°40’33’’ ÷ 3=
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''
Bons estudos!!
