洗个澡taking a bath为什么要加taking -
29573边毛

： 供参考:由己知条件得S⊿ABC=1/2*1*√3=√3/2,又S⊿ABC=1/2﹙AO·BO+BO·CO+CO·AO﹚sin120º =√3/4﹙AO·BO+BO·CO+CO·AO﹚ ∴AO·BO+BO·CO+CO·AO=2;………………① 又余弦定理,得 AO²+BO²+AO·BO=4,BO²+CO²+BO·CO=3,CO²+AO²+CO·AO=1,∴AO²+BO²+CO²=3……………………………② ﹙AO+BO+CO﹚²=AO²+BO²+CO²+2﹙AO·BO+BO·CO+CO·AO﹚ =3+2*2=7 AO+BO+CO=√7.
