Ответ:

нехай <1=х°, тоді <2=х+25°

оскільки кут1 + кут2=180°, то маємо рівняння:

х+х+25=180

2х+25=180

2х=180-25

2х=155

х=77,5

х+25=77.5+25=102.5°

Ответ:

102,5°,  77,5°

Объяснение:

Нехай ∠1=х°, тоді ∠2=х-25°

х+х-25=180

2х=205

х=102,5

∠1=102,5°,  ∠2=102,5-25=77,5°

Television is doing a great harm. It is a real monster. How often we hear statements like this . Television has not been with us all the time , but we are already beginning to forget what the world was like without it. What did we use to do before there was television ? First of all , we never found it difficult to so end our free time . We used to enjoy civilized pleasures. For instance , used to have hobbies ,we used to entertain our friends and be entertained by them ,we used to go outside for our amusements to theaters ,cinemas,restaurants and sporting events . We even used to read books and listen to music . All that belongs to the past. Now all our free time is regulated by the "magic box" . We rush home to be in time for this or that programmer . A sandwich and a glass of tea will do - anything if only it doesn't interfere with the programme. Whole generations are growing up addicted to the Telly . Food is left unbeaten,homework undone and sleep is lost. It is now standard practice for mother to keep the children quiet by putting them in the living -room with the Telly alone: it doesn't matter what the children will watch- what so long as they are quiet. Television encourages passive enjoyment. It is so easy to sit in our armchairs watching others working . Little by little .televigsion cuts uses off from the real world. We get so lazy ,we choose to spend a fine day in semi,- darkness ,glued to our sets, rather than go into the world itself. Television is a splendid means of communication , but it prevents us from communicating with each other. We only understand it when we spend a holiday by the sea or in the mountains , far away from civilization , in quiet , natural surroundings.
