What is the angle between the hour hand and the minute hand on the clock at 8:20?

At 8:20, when the hour hand passes 8, between 8 and 9, the minute hand points to 4, the degree of 20 minutes is 20 × 0.5 = 10 ° and the angle between the minute hand and 8:00 is 4 × 30 = 120 ° so the angle between the hour hand and the minute hand on the clock face is 120 ° + 10 ° = 130 °

The clock goes from 8:15 to 8:30, and the minute hand turns_____ Degrees. The clock's turning_____ The angle between minute hand and hour hand is degree

When the clock goes from 8:15 to 8:30, the minute hand turns 90 degrees, and the hour hand turns 7.5 degrees (from 8 to 9, 30 / 4 = 7.5 degrees). The angle between the minute hand and the hour hand is 75 degrees

At 8:30, what is the degree of the angle between the hour hand and the minute hand? At 3:30, what is the degree of the angle between the hour hand and the minute hand
