Ответ:
Решение:
В одном градусе содержится 60 минут.
- \( 1^{\circ} = 60' \)
- \( 30^{\circ} = 30 \times 60' = 1800' \)
- \( 90^{\circ} = 90 \times 60' = 5400' \)
- \( 0^{\circ} = 0 \times 60' = 0' \)
- \( 8^{\circ} = 8 \times 60' = 480' \)
- \( 13^{\circ} = 13 \times 60' = 780' \)
Ответ: 1° = 60', 30° = 1800', 90° = 5400', 0° = 0', 8° = 480', 13° = 780'.
