Question

What is the angle between two hands of a clock when the time in the clock is $9^{\prime }O$ clock?

Answer 1

The time in the clock is $9^{\prime }O$ clock.

We can clearly see from the figure, angle between the hands is ${90}^{\circ }$ when the time is $9^{\prime }o$ clock.

Hence, the angle is ${90}^o$ or $Rightangle$.
