Пояснення:

Чтобы найти длину АК, нам нужно использовать теорему косинусов:

AK = BC / cos(angle A) = 4 / cos(30) = 4 / (√3/2) = 8√3/√2

Таким образом, длина АК равна 8√3/√2.

Dear friend,

My name is Wendy. I live in London, England. I am twelve years old. My birthday is on the 12th of May. I live with my mum and dad. I haven't got any sisters or brothers. I go to Hillside School. My school is great but it isn’t very big. I’m in class 4a. There are twenty pupils in my class. I like my classmates. They are very friendly. Have you got any friends in your class? My favourite subjects are English and Music. I don’t like Maths because I’m not very good at it. What’s your favourite subject? I like reading books in my free time. I can sing and dance quite well. What about you? I hope to hear from you soon.

Yours,

Wendy
