What is the angle between the hands of a clock at 11:30?
Answer:
165°
Substitute H=11 and M=30 into the formula |30H - 5.5M|. We get |30(11) - 5.5(30)| = |330 - 165| = |165| = 165°.
1982
What is the angle between the hands of a clock at 10:30?
Answer:
135°
Using the angle formula |30H - 5.5M|: |30(10) - 5.5(30)| = |300 - 165| = |135| = 135°.
1983
What is the angle between the hands of a clock at 9:30?
Answer:
105°
Applying the formula |30H - 5.5M|: |30(9) - 5.5(30)| = |270 - 165| = |105| = 105°.
1984
What is the angle between the hands of a clock at 8:30?
Answer:
75°
Substitute H=8 and M=30 into the formula |30H - 5.5M|. We get |30(8) - 5.5(30)| = |240 - 165| = |75| = 75°.
1985
What is the angle between the hands of a clock at 7:30?
Answer:
45°
Using the formula Angle = |30H - 5.5M| with H=7 and M=30 gives |30(7) - 5.5(30)| = |210 - 165| = |45| = 45°.
1986
What is the angle between the hands of a clock at 6:30?
Answer:
15°
Applying the formula |30H - 5.5M|: |30(6) - 5.5(30)| = |180 - 165| = |15| = 15°. At 6:30, the hour hand has moved halfway to 7, while the minute hand is at 6.
1987
What is the angle between the hands of a clock at 5:30?
Answer:
15°
Substitute H=5 and M=30 into the formula |30H - 5.5M|. We get |30(5) - 5.5(30)| = |150 - 165| = |-15| = 15°.
1988
What is the angle between the hands of a clock at 4:30?
Answer:
45°
Using the formula Angle = |30H - 5.5M| with H=4 and M=30 gives |30(4) - 5.5(30)| = |120 - 165| = |-45| = 45°.
1989
What is the angle between the hands of a clock at 3:30?
Answer:
75°
Using the angle formula |30H - 5.5M|: |30(3) - 5.5(30)| = |90 - 165| = |-75| = 75°.
1990
What is the angle between the hands of a clock at 2:30?
Answer:
105°
Applying the formula |30H - 5.5M| with H=2 and M=30 gives |30(2) - 5.5(30)| = |60 - 165| = |-105| = 105°.
