Answer:
30°
Step-by-step explanation:
In a 12 hour clock, at exactly 1 o'clock the large hand and the small hand show 12 and 1 respectively.
So, there is an arc length of 5 minutes between them.
Now, a total of 60 minutes of rotation gives 360° rotation.
Therefore the 5 minutes of rotation will give [tex]\frac{360 \times 5}{60}= 30[/tex] degree.
Therefore, at 1 o'clock the two hands will make a 30° angle. (Answer)
