'Six Minutes Past Eight' printed from https://nrich.maths.org/
At 8 o'clock, the obtuse angle between the hands of the clock is 120 °. In the following six minutes, the minute hand turns through an angle of 36 ° whilst the hour hand turns through an angle of 3 ° in the same direction (clockwise!). So the obtuse angle between the hands increases by 33 °, to 153 °.
