因为三角形ADE相似于三角形ABC
AD:AB=DE:BC
所以AD:4.4=1.4:1.6
解得AD=3.85
所以BD=AB-AD=4.4-3.85=0.55

The emergence of high-heeled shoes, the French King Louis XIV had to make up for deficiencies figure invented. However, when it is worn on a woman's foot after it played a really wonderful role, it is no longer simply to make up for height, but after wearing high heels, naturally, can make a woman presents out, like a ballet dancer in general, heads held high the graceful posture, and the higher the heels, the effect is more evident.
Magic of high heels
Of course, as Lady Gaga general, wearing the stilts in general, would seem daunting, so the ideal height is 10 ~ 12cm, like a "Sex and The City" in the love of shoes to actress Carrie's madness Manolo Blahnik's favorite brand produced, just the right height, so that women walking up and swaying, but not so very difficult to control, so even a pair sold for $ 400 can also be in short supply!
Of course, perhaps a woman would think that wearing such high heels, action is difficult to ease, even those wearing high heels often jump in the program the subject of small S admits the country, long legs wearing high heels just about to explode ! However, you need to know is, this did not used to high heels of the Long March, in most of the time, you just need it to lengthen your leg line and allow you to automatically render chest abdomen state. Otherwise, why do so many people looked after the Spring Festival,manolo blahnik shoes, the famous supermodel legs curve feel disappointed? Not because she was wearing a pair of flat shoes it? Supermodel like this, for the average person, do not you dare high heels do not believe this magical effect?
Wear high heels have enough gas field
Worked hard in the workplace is more than one woman had told me that when major events occur, such as negotiating with others, or to meet with important people, she will wear the highest heels, however, can not have inferior the illusion of it! So, that is why the "Du are" in the handbag for the reasons for replacing two pairs of shoes at any time! wearing high heels, in a natural upright posture immediately after the third emboldened are hard!
Not just white-collar workers were the case, even such as Margaret Thatcher, so Hillary's "Iron Lady", in the face of major negotiations, they will choose to come to face the high-heeled shoes, although a high degree of 5cm may be more subtle or so, but at least is a psychological suggestion, so he will not fall into disadvantage of the state.
Of course, not without wearing flat shoes can be a powerful aura of the female distribution, but note that this group of people most of the body itself has been high enough, and for general petite women, high heels is still a shape gas field's secret weapon, but the premise is, you have to choose allows you to move freely a height, and will not let a false impression of style!
High heels are always the most popular party, the ultimate equipment
In November last year, the first phase of "The X-Factor" program, the petite singer Kylie Minogue is known for wearing a pair of nail decoration and inlaid with precious stones, heel height up to 18cm in Christian Louboutin ankle boots and boarded the program. After just a broadcast program, this cost as much as 2,325 pounds, the famous British department store Selfridges called the Ministry of Women is the most expensive high heel party shoes, immediately sold out of stock, waiting lists have a long string. Selfridges spokesman said, "high heels are always the most popular party, the ultimate equipment. This season is no exception."
So, you can almost understand why the T would be better and high heels on stage, but also more and more gorgeous, all because they have a huge market. The so-called "It Shoes", just as was the "It Bag" as women have become the goal,manolo blahnik heels on sale, especially in some major party season or the occasion, they are more willing to spend big bucks to buy under this beloved ornament, sometimes knows very little chance to wear, but also willingly. You know, this looks like Cinderella going to wear the glass slipper before the party, as the eyes can win admiration from head to toe had to meticulously, especially in high heels, it is most important to know , fight to the last fight is the details. So, why high heels are the ultimate weapon, you should understand!
