22题:角2 五十四度 角BOE 五十四度
23题 因为CD垂直AB,EF垂直AB,所以 EF平行CD(垂直于同一条直线的两直线互相平行)
又因为角BEF=角CDG,且EF平行CD 所以 DG平行BC(内错角相等,两直线平行)
又因为 DG平行BC 所以,角B+角BDG=180°(两直线平行,同旁内角互补)
欢迎追问哦亲^^

22: 答: 2*角2 = 3 *角1 (1),据上下文必有,角2+角1(两直线相交,对角相等) = 90度(2),所以 由(1)得角2=3/2 角1(3),代入(2),得到 5/2角1 =90度,于是角1 = 90 *2 / 5 度 = 36度; 角2=54度, 角BCE =90度+角2 或 180度-角1 = 144 度;
23:即证明DG 平行于BC;
因两个垂直关系...

22. ∠1+∠2=90°,∴∠1=90°-∠2
因为2∠2=3∠1,
所以2∠2=3(90°-∠2),所以∠2=54°,∠1=36°
∠DOE=∠2,对顶角相等,所以∠DOE=54°

23.∵CD垂直于AB, EF垂直于AB,所以CD//EF
所以∠FEB=∠DCB(同位角相等)
∵∠BEF=∠CDG,
所以∠DCB=...

1、把200千米的水引到城市中来,这个任务交给了甲,乙两个施工队,工期50天,甲,乙两队合作了30天后,乙队因另有任务需离开10天,于是甲队加快速度,每天多修0.6千米,10天后乙队回来,为了保证工期,甲队速度不变,乙队每天比原来多修0.4千米,结果如期完成.问:甲乙两队原计划各修多少千米?
设甲乙原来的速度每天各修a千米,b千米
根据题意
(a+b)×50=200(1)
10×(a+0.6)+40a+30b+10×(b+0.4)=200(2)
化简
a+b=4(3)
a+0.6+4a+3b+b+0.4=20
5a+4b=19(4)
(4)-(3)×4
a=19-4×4=3千米
b=4-3=1千米
甲每天修3千米,乙每天修1千米
甲原计划修3×50=150千米
乙原计划修1×50=50千米
2、小华买了4支自动铅笔和2支钢笔,共付14元;小兰买了同样的1支自动铅笔和2支钢笔,共付11元.求自动笔的单价,和钢笔的单价.
设自动铅笔X元一支 钢笔Y元一支
4X+2Y=14
X+2Y=11
解得X=1
Y=5
则自动铅笔单价1元
钢笔单价5元
3、据统计2009年某地区建筑商出售商品房后的利润率为25%.
(1)2009年该地区一套总售价为60万元的商品房,成本是多少?
(2)2010年第一季度,该地区商品房每平方米价格上涨了2a元,每平方米成本仅上涨了a元,这样60万元所能购买的商品房的面积比2009年减少了20平方米,建筑商的利润率达到三分之一,求2010年该地区建筑商出售的商品房每平方米的利润.
(1)成本=60/(1+25%)=48万元
(2)设2010年60万元购买b平方米
2010年的商品房成本=60/(1+1/3)=45万
60/b-2a=60/(b+20)(1)
45/b-a=48/(b+20)(2)
(2)×2-(1)
30/b=36/(b+20)
5b+100=6b
b=100平方米
2010年每平方米的房价=600000/100=6000元
利润=6000-6000/(1+1/3)=1500元

以下地名和餐厅名纯属虚构
我不得不承认,我打得很辛苦.
Tommy,one of my best friend from America,is finally comming to Shenzhen to spend his summer holiday with my family.
I really did a lot of planning before my friend's arrival.
One of the most important thing to do is,to let him try the proper Chinese food.
A Shenzhen native who knows his food.As a Chinese food aficionado,I would show Tommy that Happy Vally Restaurant is THE right place to go to get great Chinese food all the time.
Nestled in the middle of a strip mall on Jiangnan Road in the City Center,Happy Vally Restaurant doesn't stand out and wouldn't be a place you would choose if you didn't specifically decide to go there.
But after one taste,I already know that this will be one of those staple restaurants to visit when I'm in the mood for good food.
one of my favorite dish here is the salt and pepper pork ribs,it's perfectly executed with just the right amount of flavor & crisp,but still juicy on the inside.
Other famous dishes here such as Szechuan Chicken,Ginger Scallion Chicken,the Fried Oysters,and the Sauteed Watercress are so delicious too.
In fact,it's hard not to order all of these everytime I go,but there's so much else that's good that I have to let the rest of my family do the ordering so I can try other dishes.
However,With standard Chinese restaurant decor and fluorescent lighting,we are definitely not in a fancy Chinese restaurant,but it's ok because the star here is the food.I would go so far as to say this is the best Chinese Food in the area,even in the whole town.
Well,I am really looking forward to showing my friend why Chinese food is the best in the world.
