va rog mult!!

urgent!!!!!??

Answer 1

a) 44°38'15"+29°46'28"

calculam suma secundelor 15"+28"=43"

calculam suma minutelor 38'+46'=84'=1°24'

calculam suma gradelor 44°+29°+1=74°, deci suma finala va fi

74°24'43"

b) 66°58'11"+17°24'43"

11"+43"=54"

58'+24'=82'=1°22'

66°+17°+1°=84°, rezultat final=84°22'54"

c) 100°50'42"-83°55'28"

42"-28"=14"

deoarece 55'>50' vom transforma 1°=60' in minute sivom avea

(60'+50')-55'=110'-55'=55'

99°-83°=16°, rezultatul final=16°55'14"

d) 108°12'14"-57°57'16"

1'14"-16"=74"-16"=58"

1°11'-57'=71'-57'=14'

107°-57°=50°, iar rezultatul final va fi=50°14'58"
