What is the angle between the hands of a clock at 5:40?
Answer:
70°
Using |30(5) - 5.5(40)| = |150 - 220| = |-70| = 70°.
1952
What is the angle between the hands of a clock at 4:40?
Answer:
100°
Substitute H=4 and M=40: |30(4) - 5.5(40)| = |120 - 220| = |-100| = 100°.
1953
What is the angle between the hands of a clock at 3:40?
Answer:
130°
Using |30(3) - 5.5(40)| = |90 - 220| = |-130| = 130°.
1954
What is the angle between the hands of a clock at 2:40?
Answer:
160°
Substitute H=2 and M=40: |30(2) - 5.5(40)| = |60 - 220| = |-160| = 160°.
1955
What is the angle between the hands of a clock at 1:40?
Answer:
170°
Using |30(1) - 5.5(40)| = |30 - 220| = |-190| = 190°. The interior angle is 360° - 190° = 170°.
1956
What is the angle between the hands of a clock at 12:20?
Answer:
110°
For 12:20, use H=0 and M=20. |30(0) - 5.5(20)| = |-110| = 110°.
1957
What is the angle between the hands of a clock at 11:20?
Answer:
140°
Substitute H=11 and M=20: |30(11) - 5.5(20)| = |330 - 110| = 220°. The interior angle is 360° - 220° = 140°.
1958
What is the angle between the hands of a clock at 10:20?
Answer:
170°
Using |30H - 5.5M|: |30(10) - 5.5(20)| = |300 - 110| = 190°. Since this is a reflex angle (> 180°), the interior angle is 360° - 190° = 170°.
1959
What is the angle between the hands of a clock at 9:20?
Answer:
160°
Applying the formula |30H - 5.5M|: |30(9) - 5.5(20)| = |270 - 110| = |160| = 160°.
1960
What is the angle between the hands of a clock at 8:20?
Answer:
130°
Substitute H=8 and M=20 into the formula |30H - 5.5M|. We get |30(8) - 5.5(20)| = |240 - 110| = |130| = 130°.
