The angle between the hour hand and minute hand of a clock at time 9:00 is _______ degrees.

 

Correct option is C

To find the angle between the hour hand and the minute hand of a clock at 9:00, we use the formula:

where:

• H = Hour

• M = Minutes

At 9:00, we substitute H = 9 and M = 0:

Since a clock is circular (360° total), we always take the smaller angle. The two possible angles are:

1. 270° (the larger angle)

2. 360° - 270° = 90° (the smaller angle)
