Duke of Zhou alarm clock minute hand _ Mengmeng alarm clock

Help: at 2: 30 on the alarm clock, what is the angle formed by the hour hand and the minute hand?

It is an obtuse angle, 105 degrees.

Each square of the clock can be regarded as 30 degrees, so when the indication is 2: 30, the minute hand is at 6, and the hour hand is between 2 and 3, then it is 15 degrees, plus 3 to 6, these three 30 degrees, the answer should be 105 degrees!
