tks mn
em chả hiểu gì cả, nhung đề bài đây
nếu tổng của tất cả các góc trong 1 đa giác lồi là 1080 độ . vậy đa giác có bao nhiêu đường chéo??????????

The word "telephone" means hearing the sounds produced at a distance, just as we see distant objects through a "telescope" or we see things happening miles away through "television". The television was invented more thanone hundred years ago by Alexander Gragam Bell, an American. It is now very extensively used everywhere. In Vietnam, most of the people have their own telephones in their homes. It makes us possible to talk to our friends far away without all they way to their homes.
In actually working it appears to be simple. It has a transmitter into which you speak and a receiver at which you hear; and these two are now combined in the same small instrument, one at each end. The two persons who want to speak have each an instrument. There is a connecting write andelectric battery by the side of each, or there is a common connecting station. it is the electric current enables the sound vibrations to be reproduced at the other end, and the person at the end heara the talk of his friend.
Its working is marvelous, though simple. Two persons can now carry on a conversation with each other while both are lounging on their easy chairs. There is thus no need now to leave your house to talk to a friend on any business. It saves time, trouble and expense.
*Question:
1. What does the work "telephone" mean?
=>..............................................................
2. Who invented the telephone?
=>..............................................................
3. When was the telephone invented?
=>..............................................................
4. Why do they like using the telephone?
=>..............................................................
5. So most of the Vietnamese have their own telephone in their homes?
=>..............................................................

Let ABC be a triangle with AB = 3cm, AC = 7cm. The internal bisector of the angle BAC intersects BC at D. The line passing through D and parallel to AC cuts AB at E. Find the measure of DE.
Answer: DE = ..........cm.
Write your answer by fraction in simplest form
ta có:
\(\frac{BD}{DC}=\frac{AB}{AC}=\frac{3}{7}\)( do AD là tia phân giác của \(\widehat{BAC}\))
\(\Rightarrow\frac{BD}{BC}=\frac{3}{11}\)
Ta có:
\(\frac{ED}{AC}=\frac{BD}{BC}=\frac{3}{11}\Rightarrow ED=\frac{3AC}{11}=\frac{3.7}{11}=\frac{21}{11}\)
