A Correct answer
Explanation

Angle = |30H - 5.5M|. H=8, M=20. Angle = |30*8 - 5.5*20| = |240 - 110| = 130 degrees.

AI explanation

By applying the clock angle formula, the hour hand position at 8:20 is 8 multiplied by 30 degrees plus 20 multiplied by 0.5 degrees, resulting in 250 degrees. The minute hand position is 20 multiplied by 6 degrees, resulting in 120 degrees. The absolute difference between 250 degrees and 120 degrees is 130 degrees.
