ANSWER: 130
Explanation:
When minute hand is behind the hour hand, the angle between the minute hand and hour hand at M minutes past H hours is given by:
=> 30 * (H-M/5) + M/2
When minute hand is ahead of hour hand, the formula becomes:
=> 30* (M/5-H) – M/2
Applying the second formula as here the minutes hand is ahead of the hour hand.
=> 30* (40/5-3) – 40/2
=> 30* (8-3) – 20
=> 30*5 – 20
=> 150-20
=> 130
Thus the angle formed is 130 degrees.
