What is the angle between the hands of a clock at 9:15?
Answer:
172.5°
Using the formula Angle = |30H - 5.5M|. Here, |30(9) - 5.5(15)| = |270 - 82.5| = 187.5°. Since a clock angle is usually represented by the acute/obtuse interior angle, we subtract from 360° if it exceeds 180°. 360° - 187.5° = 172.5°.

What is the angle between the hands of a clock at 8:15?
Answer:
157.5°
Applying the formula |30H - 5.5M|: |30(8) - 5.5(15)| = |240 - 82.5| = |157.5| = 157.5°.
1973
What is the angle between the hands of a clock at 7:15?
Answer:
127.5°
Substitute H=7 and M=15 into the formula |30H - 5.5M|. We get |30(7) - 5.5(15)| = |210 - 82.5| = |127.5| = 127.5°.
1974
What is the angle between the hands of a clock at 6:15?
Answer:
97.5°
Using the angle formula |30H - 5.5M|: |30(6) - 5.5(15)| = |180 - 82.5| = |97.5| = 97.5°.
1975
What is the angle between the hands of a clock at 5:15?
Answer:
67.5°
Applying the formula |30H - 5.5M|: |30(5) - 5.5(15)| = |150 - 82.5| = |67.5| = 67.5°.
1976
What is the angle between the hands of a clock at 4:15?
Answer:
37.5°
Substitute H=4 and M=15 into the formula |30H - 5.5M|. We get |30(4) - 5.5(15)| = |120 - 82.5| = |37.5| = 37.5°.
1977
What is the angle between the hands of a clock at 3:15?
Answer:
7.5°
Using the formula Angle = |30H - 5.5M| with H=3 and M=15 gives |30(3) - 5.5(15)| = |90 - 82.5| = |7.5| = 7.5°.
1978
What is the angle between the hands of a clock at 2:15?
Answer:
22.5°
Applying the formula |30H - 5.5M|: |30(2) - 5.5(15)| = |60 - 82.5| = |-22.5| = 22.5°.
1979
What is the angle between the hands of a clock at 1:15?
Answer:
52.5°
Using the formula Angle = |30H - 5.5M|. Substituting H=1 and M=15 gives |30(1) - 5.5(15)| = |30 - 82.5| = |-52.5| = 52.5°.
1980
What is the angle between the hands of a clock at 12:30?
Answer:
165°
For times starting with 12, we can use H=0. Angle = |30(0) - 5.5(30)| = |-165| = 165°.
