Answer 1

De reținut :

60'' = 1'

60' = 1°

 

I. a) 12°15'31'' + 25°21'23'' = ( 12 + 25 )°(15+21)'(31+23)'' = 37°36'54''

c) 47°31'47'' + 52°43'32'' = (47+52)°(31+43)'(47+32)'' = 99°74'79'' = 99°(60+14)'(60+19)'' = 100°15'19''

e) 27°47'13'' + 3°52'27'' = 30°99'40'' = 30°(60+39)'40'' = 31°39'40''

g) 26°34'18'' + 18°25'42'' = 44°59'60'' = 44°60' = 45°

i) 47°29'37'' + 54°43'35'' = 101°72'72'' = 101°73'12'' = 102°13'12''

k) 27°38'42'' + 18°45'39'' = 45°83'81'' = 45°84'21'' = 46°23'21''

II. a) 85°25'47'' - 27°15'23'' = (85-27)°(25-15)'(47-23)'' = 58°10'24''

c) 41°24'32'' - 27°35'43''  = (41-27)°(24-35)'(32-43)'' = 14°(24-35)'(32-43)'' = 13°(60+24-35)'(32-43)'' = 13°49'(32-43)'' = 13°48'(60+32-43)'' = 13°48'49''

e) 74°3' - 10°45' = 64°(3-45)' = 63°(60+3-45)' = 63°18'

g) 85° - 34°28' = 51°(0-28)' = 50°(60+0-28)' = 50°32'

i) 146°23'50'' - 72°41'22'' = 74°(23-41)'28'' = 73°(60+23-41)'28'' = 73°42'28''

k) 46°21'15'' - 28°37' = 18°(21-37)'15'' = 17°(60+21-37)'15'' = 17°44'15''
