In the clock face shown below, the positions of the numbers determine congruent arcs along the circle. 28. What is the measure of the arc between any two consecutive numbers? 29. An arc is traced out by the end of the second hand as it moves from the 12 to the 4. Is it a minor arc or a major arc? 30. Starting at the 2, what number does the end of the second hand reach as it completes a semicircle? 31. When the second hand moves from the 8 to the 3, what is the measure of the arc? 32. When the second hand moves from halfway between the 1 and the 2 to 4 of the way from the 1 to the 2, what is the measure of the arc? 5 33. The second hand moves from the 3 to the 7. What is the measure of the corresponding major arc?
