度分秒计算~谢。

60°31'43''x2-45°13'30''/3+18°45'48''
把计算过程写出来哦。。谢谢啦
虽然两位都很好。可是最后的答案应该是124°46'44''...

Answer 1

=120。61’86”-45。12’90”/3+18。45’48”=121。3’26”-15。4’30”+18。45’48”=124。44’44”应该算比较详细了，先算，再进分和度！手机回答的“。”就是度哈！

Answer 2

60°31'43''x2-45°13'30''/3+18°45'48''
=120°62'86''-15°4'30''+18°45'48''
=123°103'104''
=124°44'44''

Answer 3

60°31'43''x2-45°13'30''/3+18°45'48''
=120°62'86''-15°4'30'+18°45'48''
=123°103'104''
=124°44'44''

Answer 4

60°31'43''x2-45°13'30''/3+18°45'48''
=121°3'23''-15°4'30''+18°45'48''
=139°53'41''
