Question

Find the angle formed by the arms of a clock at 12 O’clock.

Answer 1

We know that sum of angles at a point = 360° and on the face of a clock there are 12 marks on it.

Now at 12 O’clock, the hour hand and minute hand are both 12°

∴ Angle between them `= 12/12 xx 360^circ = 360°` or 0° as both hands coincide each other.
