详细一点，谢谢
　　Dear Mr Smith,　　I have come to your apartment, butit’ s a pity that you happen to be out.　　what do you think of the performances of Beijing Opera last night?Judging from thecontent expression on you face, it must have been an unforgettable experiencefor you. I ’ m very glad that youlike it. As you know, Beijing Opera is a kind of traditional Chinese opera and many foreigners like it verymuch.　　And I regret to tell you there is something wrong with the book youpurchased for me online. Its front cover is missing on its delivery. So I ’ m afraid a complaint has to be made to the shop owner to get itchanged before the deadline. Besides, I ’ d like to remind you toattend the English corner at 8:00 am thisSunday. Your presence will be greatly appreciated.　　Best wishes!　　Yours,　　LiHua
Oh.Thank you

将John改为Smith Dear John，We are going camping on yulong mountain this weekeed.There wil be 6 people being together at eight thirty this Saturday at the Railway station square.And then we will take a train to get there at eleven thirty。After enjoying a good time ，we will be back at Sunday afternoon.What we should do is to take some camping things we need，a camping tent is a must.What is more，sleeping bags, coats , water and foods are all that we need.I believ that we must have a good time we can set up our further friendship then，I hope you can join us. Looking forward to your reply.Yours，Lihua

来自丰城市荷湖小学
解：函数f（x）=x2-2ax+5的对称轴是x=a，则其单调减区间为（-∞，a]，因为f（x）在区间（-∞，2]上是减函数，所肌埂岗簧瞢毫哥桐工昆以2≤a，即a≥2．则|a-1|≥|（a+1）-a|=1，因此任意的x1，x2∈[1，a+1]，总有|f（x1）-f（x2）|≤4，只需|f（a）-f（1）|≤4即可，即|（a2-2a2+5）-（1-2a+5）|=|a2-2a+1|=（a-1）2≤4，亦即-2≤a-1≤2，解得-1≤a≤3，又a≥2，因此a∈[2，3]．

设内角分别为2x，2x，x2x+2x+x=180→x=36°那么顶角为36°若设内角分别为x，x，2x即x+x+2x=180→x=45°∴顶角为2x=90°综上所述顶角可为90°或36°
另一个是45
应该是36或45吧
刚才答错了是45。 90
傻逼你你采纳的答案是错的
