Ответ:

Всі кути трикутника разом завжди дають 180 градусів. Отже, щоб знайти величину третього кута, необхідно від відомих величин двох кутів відняти 180 градусів і отриману різницю прирівняти до величини третього кута.

Отже, величина третього кута трикутника буде:

180 градусів - 18 градусів - 71 градус = 91 градус.

Таким чином, величина третього кута дорівнює 91 градусу.

Call me Archibald. My real name isn't important. In this blog I want to share my ideas with other kids my age. It isn't always easy to talk to our parents or even friends. I'm sure you understand me.

use my dad's small digital camera. It takes great pictures.

I've got lots of photos of my friends (of one classmate especially!). I read books about superheroes like Superman. I'm not a superhero myself but I hate injustice and I'd like to have some special powers, too.

Here is some information about myself. I'm 14 years old. I play water polo. I go to the swimming pool every day except at the weekend. I'm a good swimmer and player although I'm not very tall or very strong. I'm also interested in photography. I

I haven't got any brothers or sisters. My parents work hard and spend a lot of time at work, so I'm often alone at home. My mum's a teacher. She prepares for school and she always talks
about her pupils. I sometimes get upset because maybe she thinks they're better than me. My mum says that Pete is such a good pupil. I think he reads my blog. My dad's a mechanic and he fixes cars. He tells jokes all the time and he is never serious. He thinks he has a sense of humour but his jokes aren't always funny!

I have a pet parrot. His name is James. He's got a cage in my room but he rarely stays in it. He usually flies around. He is friendly but he isn't polite; he hasn't got good manners. He never uses the toilet! He also bites computer cables and sometimes my finger! E-mail me!
