The hands of a clock show the time 12:25. What kind of angle exists between the hands of the clock?

A clock face has the numbers 1 through 12 Each number is 1/12 of a complete circle which is 360 degrees.

Each number is 360 / 12 = 30 degrees

For a clock reading 12:25, the hands are on the 12 and 5

The angle would be 30 x 5 = 150 degrees.

It is larger than 90, so could be called an obtuse angle.
