Вертикальный столб высотой 3 метра стоит рядом со стройным деревом на горизонтальной равнине. Тень от столба имеет длину 2,8 м, тень от дерева — примерно 48 м.

Выключить

Определите высоту дерева.

archery: тени от солнца падают под одинаковым углом, потому триугольники предмет-тень и для дерева и для столба - подобны. Соотношение сторон равны
3 / 2.8 = x / 48 => x = 48 * 3 / 2.8 = 51.4285714286

Britain is often regarded as "the cradle of democracy" and the Palace of Westminster: the "Mother of all Parliaments". The British state is described as a constitutional monarchy and a parliamentary system. The correct constitutional definition of Parliament is the 'Queen-in- Parliament'. A constitutional monarchy is a form of government in which a king or queen is the Head of State (the official head of the country), but an elected government has most of the real power.

Government is a group of politicians from the party with a majority in the general election. Typically, just one party has the majority, but at the moment Britain has a coalition. The head of government is the prime minister. All political power rests with the prime minister and the Cabinet, the most important committee in the British government, whose members are selected by the prime minister, and the monarch must act on their advice. Government is responsible for amending laws, making new ones, and abolishing old ones; they set the rate of taxes, plan the budget, and pursue the policies they talked about during their election campaign. The branches of the British government include:

the legislature is the supreme law-making body, which consists of the House of Commons the House of Lords, and formally the monarch;

- the executive comprises the sitting government, its Cabinet government ministries, or departments, headed by ministers, or secretaries of state, and formally the monarch; -the judiciary consists of the judges of the higher courts, formally the monarch.

The British Parliament is the name given to the House of Lords and the House of Commons. Members of Parliament come from different political parties and their role is to represent the people and to inspect the work of the Government. Both houses must approve a new law before it can be passed.
The House of Lords consists of the non-elected Lords that are hereditary or life peers. There arel,200 members and they receive no salary for their parliamentary work. The House is presided over by the Lord Chancellor. He is a political appointee of the sitting government and a Speaker (Chairman) of the House, he controls the procedure and meetings of the House; The House of Commons consists of Members of Parliament (MPs), who are elected by the

British people every 5 years. There are 650 MPs, whose great majority belongs to either the

Conservative or the Labour Party, which are the main political parties. This division emphasizes

the continuation of the traditional two-party system in British politics.

The British Constitution is only partly written and is flexible, it also has legal force. Its basic

sources are parliamentary and European Union legislation, the European Convention on Human

Rights, and decisions by courts of law.

The British monarch holds a formal role. Succession to the throne is still hereditary, but only for Protestants in the direct line of descent. Queen Elizabeth II, who is the current monarch, has a number of roles, but serves formally as the head of state, head of the three governmental branches, the commander-in-chief of the armed forces, and the supreme governor of the Church of England. She remains politically impartial and with limited powers, it means she cannot make laws, impose taxes, or spend public money. Time has reduced the power of the monarchy, and today it is broadly ceremonial, like appointing the government, opening and dissolving the Parliament, the Queen's speech, and the Royal Assent.
