Answer 1

Răspuns:

Explicație pas cu pas:

a) 26°21'32"-19°35'42" +7°24'53"

= 26°21'32" + 7°24'53" - 19°35'42"

= 33°45'85'' - 19°35'42''

= 14°10'43''

b) 71°24'35" - 15°36'42" + 12°48'54"

= 71°24'35" + 12°48'54" - 15°36'42"

= 83°72'89'' - 15°36'42''

= 68°36'47''

c) 43°26'42" - 21°32'51" + 7°18'43"

= 43°26'42" + 7°18'43" - 21°32'51"

= 50°44'85'' - 21°32'51"

= 29°12'34''
