At 2:30 AM the minute hand will be vertically downward, pointing towards 6 on the dial.
To indicate 5:45, the alarm’s hand should be 15 minutes away from the number 6 in anti-clockwise direction.
So, we just need to calculate the angle traversed by the hour hand in 15 min.
Hours hand covers 30 in 1 hour. So it will cover 7.5 in 15 minutes.
