扫描下载二维码139.6已知11/a+11/b +11/c =143/210 ,且a≠b≠c,求a、b、c各是多少?请说明过程.
側面臚橗耫
11/a)+(11/b)+(11/c)=143/210 设a*x=b*y=c*z=210 由于a≠b≠c,所以x≠y≠z 原式变为： (11x/ax)+(11y/by)+(11z/cz)=143/210 (11x+11y+11z)/210=143/210 x+y+z=13 由于a*x=b*y=c*z=210 所以a、x、b、y、c、z都是由210的质因数构成的数 210=1*2*3*5*7 x+y+z=13 (1)1+2+10=13, a=210,b=105,z=21 11/210+11/105+11/21=143/210 (2)1+5+7=13, a=210,b=42,z=30 11/210+11/42+11/30=143/210 (3)2+5+6=13, a=105,b=42,z=35 11/105+11/42+11/35=143/210
有简单点的方法不？

用科学计算器计算 点shift+sin 也就是sin-1 接着输入值 然后点一下由数转化到度数的键就OK了!别人指的6.度 69.3577772度 44.度 81.度 不应该加度,这是十进制到度后应是6度14分25.37秒69度21分28秒44度50分17.75秒81度58分31.08秒
