Question

calculati
a] 44* 38 ' 15 " +29 * 46 ' 28" =
b] 66 * 58 ' 11 " +  17 * 24 " 43 " =
c] 100 * 50 ' 42 " - 83 * 55 ' 28 " =
d] 108 * 12 ' 14 "- 57 * 57 ' 16 "=

Answer 1

a) *reprezinta grade  stim ca de ex.44*38'15''=43*+38'+15''
⇒(44*+29*)+(38'+46')+(15"+28")=83*+84'+43''=(83*+1*)+(84'-60')+43''=84*+24'+43"=
=84*24'43''
b)⇒=(66*+17*)+(58'+24')+(11''+43'')=83*+82'+54''=(83*+1*)+(82'-60')+54''=84*+22'+54''=
=84*22'54''
c)⇒=(100*-83*)+(50'-55')+(42''-28'')=17*+(50'-55')+14''=(17*-1*)+(110'-55')+14''=16*+55'+14''=
=16*55'14''
d)⇒ (108*-57*)+(12'-57')+(14''-16'')=51*+(12'-57')+(14''-16'')=(51*-1*)+(72'-57')+(14''-16'')=
50*+15'+(14''-16'')=(50*-1*)+(60'+15')+(14''-16'')=49*+75'+(14''-16'')=49*+(75'-60')+(74''-16'')=
49*+15'+58''=49*15'58''
am facut detaliat ca sa intelegi dar se poate face si direct transformi gradele in minute, minutele in secunde s.a.md

Answer 2

probabil steluta semnifica gradul?
a)=  74,24,43
b)=   84,22,54
c)=  27, 35,14
d= 50,55,38
