请发照片,如果是下面的那两题,我可以帮你做.1.因为直角三角形30°角所对直角边等于斜边一半,已知斜边AD为4,所以直角边AE为2,根据勾股定理得另一直角边ED=AF=2根号3,所以边长EF=2根号3-2=2（根号3-1） 【就是这个思路,算没算错我就不知道了,自己按部就班再算一遍】 2.因为ABC是等边△,所以∠A=∠B=∠C=60°,有因为平行,所以∠D=∠E=60°,即三个角皆为60°,三角形ADE是等边三角形.【简写,请自己完善】 最后,

1.(1)60x4/5=48
(2)60÷5/4=48
(3)60x(1-1/5)=48

第一：单词必须要过关。我记单词的时候从来没有写一个字，几乎全是读过来的吧(除了个别整理的时候要在本子上写一写)。我为什么要建议大家读着记单词呢？其实里面的好处多多！首先我们看了一遍单词才能读出来，其次我们读了一遍再者我们听了一遍最后我们的大脑记了一遍(也可以说强化了一遍)其实对于精力集中的同学来说如果边读边思考那么他还在心里又记了一遍！这样一来读一遍单词我们其实足足记了五遍！其中的好处大家试试后便...
