Відповідь:

Покрокове пояснення:

Всі сторони у ромба однакові, тому одна сторона: 16/4=4 см.

Площа обчислюється за формулою а^2sinα, тому 8√2 = 16sinα

sinα = √2/2 = 45°. Два кути по 45°, інші два по 135°.

2. Reading Read the text and do the tasks. Welsh Mind and Character The Welsh are a nation and they are conscious of it. However similar they may be in appearance, as soon as they begin to speak the difference is clear. The Welsh are quick and impetuous in speech. They are highly-gifted in the art of self-expression in words, they speak fluently and confidently. They are not afraid of being poetic in speech, of using bright and pictorial descriptions of men and events in ordinary conversation. The Welsh like listening to good speaking and they are critical as an audience. They are a nation of singers. Wherever they meet, they sing. There is no need to “arrange” singing, it will happen spontaneously and it will be good. This custom dates back to a period long before any written music was available to the people. You will not travel far in Wales without finding a choir. Even in small villages men and women gather together to practice singing and then a public performance of the works they have learnt. Sometimes members of smaller choirs unite to form one big choir and to give a series of festival performances of choral works. Only rare these choirs have a professional conductor. Each village or town choir can find a local musician capable of conducting it. The standard of singing is high and the love of good music is widespread. The Welsh are especially proud of their language. When you travel you can see road signs in Welsh all over Wales. Most Welshmen speak both Welsh and English, and there is literature in two languages. Welsh literature has an ancient history and has made its contribution to the legends of King Arthur in Britain. Prose, romance and poetry are its chief glory. Novels and short stories in Welsh, Welsh periodicals, books on research and history, books on poetry — these all are being produced at an ever increasing rate. The love of reading is widespread in Wales. Task 1 True or False. 1. We can differentiate the Welsh from the English by appearance. 2. The Welsh are proud of their nation. 3.
