答
120°23’44’’+36°50’28″
=156°73‘72“
=156°74‘12“
=157°14‘12“
85°23’-29°40’
=84°83’-29°40‘
=55°43’
108°18’-56.5°
=107°78’-56°30‘
=51°48’
答
120°23’44’’+36°50’28″
=156°73’72’’
=156°74’12’’
=157°14’12’’
85°23’-29°40’
=84°83’-29°40’
=55°43’
108°18’-56.5°
=108°18’-56°30'
=107°78’-56°30'
=51°48’
答
120°23’44’’+36°50’28″
=156°73’62’’
=157°14’2″
85°23’-29°40’
=84°83’-29°40’
=55°43’
108°18’-56.5°
=108.3°-56.5°
=51.7°
