What is the angle between the clock hands at 12:55?

Correct option is C

Given: The clock hands at 12:55.

Formula Used:

Angle between = $$\Big| 30H - \frac {11}{2}M\Big|$$

= $$\Big| 30\times12 - \frac {11}{2}\times55\Big|$$

= $$\Big| 360 - \frac {605}{2}\Big|$$

= $$\Big| \frac {720 - 605}{2}\Big|$$

= $$\Big| \frac {115}{2}\Big|$$

= 57 $$\frac {1}{2}$$​​°

Thus, correct option is (c).
