hour hands:
the hour hand is located at position 0.
minute hands:
the minute hand is located in position 6.
The angle of each position of the watch is:
360 * (1/12) = 30
The difference of position between the hands is:
6-0 = 6
Therefore the angle between hands is:
(6) * (30) = 180 degrees:
Answer:
there are 180 degrees in the smaller angle formed by the minute and hour hands on a clock at 12:30
