Сумма всех углов треугольника равна 180град, тогда угол С=70град, угД=68, найдем угЕ=180-(68+70)=180-138=42град
Рассмотрим треуг.СFE, в котором угС=35град по условию, угЕ=42град мы нашли выше, осталост найти угF или уголСFE=180-(35+42)=180-77=103град
When the body is healthy, the mind will also be healthy. Different types of food contain different nutrients for our body. Some supply us with carbohydrates, some with proteins or fats, some with vitamins and minerals, etc. Many people think that fat is bad for people and they try to cut down on it. There is even a special line of products, called low-fat.
