1) 180-145=35
Відомо, що кут М прямий отже дорівнює 90 градусів
Сума всіх сторін трикутника=180 градусів
2) 180-(90+35)=55
Отже кут А дорівнює 55 градусів

READING
Task 2. Read the text.
Healthy lifestyle
Today healthy lifestyle is becoming more and more popular both with
the old and the young. People have become more health-conscious. They
say that the greatest wealth is health. And it's so true. The healthier we
are, the better we feel. The better we feel, the longer we live.
Keeping fit and going in for sports is also important for our health.
Lack of exercise in our life is a serious problem. In big cities people spend
hours sitting in front of computers, TV-sets and other gadgets. We walk
less because we mainly use cars and public transport. We certainly don't
have to be professional sportsmen, but we should visit fitness clubs, go
jogging, walk much, swim, go cycling or roller-skating or just dance.
Doctors say that regular moderate physical activity is necessary for our
body because it protects us from strokes and heart diseases, flue and
obesity.
We must understand the harm of bad habits for our health. Smoking,
drinking or taking drugs mean serious illnesses and even death from lung
cancer or liver diseases, for instance. Cigarettes kill about 3 million
heavy-smokers every year. Drug addicts die very young. So I think there
is no place for bad habits in a healthy way of life.
Taking a proper rest and getting enough sleep, from 8 to 10 hours
daily, are also great healthy habits. Sleep the food for our brain and the
rest for our muscles. Moreover we should avoid getting nervous or
worried for no reason.
Healthy way of life concerns our body, mind and soul. Healthy people live
longer, they are more successful and they enjoy their life. I believe that it's
not difficult at all to follow these simple rules, and they are worth it.

1. Healthy lifestyle is becoming popular with the young.
