Ответ:

Противоположные углы ромба равны. Сумма внутренних углов четырехугольника равна 360°.

Отсюда: Второй меньший угол равен 39°.

Сумма двух других углов: 360 - 2*39 = 282°

Бо'льшие углы ромба: 282 : 2 = 141°

Ответ: 46°; 46°; 141°; 141°

My working day
I usually get up at 7 o'clock in the morning. I do my morning exercises, but not always, make my bed, wash and dress. Then I have breakfast. At 8 o'clock I leave home and go to school. As a rule I come to school in time as the lessons begin at 9 o'clock. I live not far from school and it usually takes me 15 minutes to get to school on foot. Usually we have 6 or 7 classes every day and after classes I return home.
At 3 o'clock I have dinner and rest a little. After that I do my homework and help my mother about the house if she needs my help. Then I have supper and if the weather is good I go for a walk with my friends and if the weather is not good I stay at home something I watch TV; sometimes I listen to music or chat with my friends over the telephone.
I never work late in the evening. At 11 o'clock I usually go to bed but sometimes I watch television till late in the evening and that's why I may go to bed very late. But I always remember the proverb: "Early to bed and early to rise makes a man healthy wealthy and wise."
Questions:
1. When do I usually get up on week days?
2. What do I do when I have free time?
3. Is my school close to me?
4. When do I usually go to bed?
