It takes 12 hours for the hour hand to go around (360 degrees), that is, the speed is 360 degrees 12 hours = 360 degrees (12*60) minutes = degrees minutes, and it takes 1 hour for the minute hand to go around (360 degrees), that is, the speed is 360 degrees 1 hour = 360 degrees 60 minutes = 6 degrees minutes, the clock face (360 degrees) is divided into 12 equal parts, so each part (between two adjacent numbers) is 30 degrees, so after x minutes, the angle at which the hour hand travels is degrees, and the angle at which the minute hand travels is 6x degrees, From 5 o'clock to 5:06 a.m., the hour and minute hands have traveled for 6 minutes, the hour hand has traveled 6* degrees, and the minute hand has traveled 6*6=36 degrees, 36-3=33, so the angle between the hour hand and the minute hand at 5:06 is 33 degrees.
-
If it reaches 5 o'clock, the angle between the hour and minute hands is 360*5 12=150 degrees.
The speed of the hour hand is 6 degrees, and the speed of the minute hand is 6 degrees.
From 5 o'clock to 5:06 o'clock, the two movements at the same time, it can be seen that the component needle is chasing the hour hand at a speed of 6 degrees and minutes for 6 minutes.
Then, the velocity of the minute hand relative to the hour hand is (degrees minute, then the hour hand is stationary, then the minute hand has traveled 6*(degrees.
Because the hour hand is stationary, the angle sought is 150-33=117 degrees.
-
Relative to 12, the hour hand 5 * 30 + 3 = 153 degrees, the minute hand 360 10 = 36 degrees.
Therefore, at 5:06 a.m., the angle between the hour and minute hands is 153-36 = 117 degrees.
-
117 degrees. 4*30 Angle of the hour and minute hands when they are not moving.
360 30)*(12 60) The number of degrees that the minute hand travels more.
360 30)*(6 60) The number of degrees that the hour hand travels more.
4 * 30 degrees - (360 12) * (1 5) + (360 30) * (6 60) = 120-6 + 3 = 117

I have a formula
30m-11 2n in absolute terms.
m is the hour. n is a minute.
In the end, it was 117 degrees.
-
The hour hand is 360*(6 60*1 12)+360*5 12=153° at 12 o'clock
The minute hand is 360*6 60=36° at 12 o'clock

Travel issues. At 5 o'clock, the angle is 360° 5 12 = 150° 5 minutes: hour hand 360° 5 60 1 12 = minute hand: 360° 5 60 = 30°
So the angle at this time: 150-30°+, 1, the angle is 120°Can you talk about the process Thank you 12 o'clock to 3 o'clock there are 3 hours, and then the angle between 12 o'clock and 3 o'clock is 90 °, 90 ° is divided into 3 hours, so the auspicious pin is 30 degrees between an hour and another hour, the minute hand and the hour hand are separated by 4 spaces, each empty degree is 30 degrees, 4 30 = 120 °.
There are no diagrams, and they are not very detailed. It should be understandable that there are 3 hours from 12 o'clock to 3 o'clock, and then the angle between 12 o'clock and 3 o'clock is 90 degrees, and 90 degrees is divided equally by the 3 hours of stupid banquet leakage, so the degree between one hour and another hour. 0,

Itinerary problem pants waiter. At 5 o'clock, the angle is 360° 5 Hu 12 = 150° 5 minutes: hour hand 360° 5 60 1 12 = minute hand: talk block 360° 5 60 = 30°
So the angle at this time: 150-30°+
-
The minute hand is 60 minutes 360 degrees, and when the minute hand is 8 minutes 48 degrees, the sharp blue needle is 60 minutes 30 degrees and 8 minutes 4 degrees and swims 12 to 5,150 degrees, so the solution is 150-48 + 4 degrees for silver milling, so it is 106
-
The minute hand walks 6 degrees per minute, the hour hand walks every minute, and the angle between the minute hand and the hour hand is 60 degrees when it is set at 5 o'clock x minutes, according to the title: ( Solution: disturbing the first x = 16 and 4 11 minutes;
or:( Solution: x=38 and 2 11 points.
That is, at 5:16 and 4 11 or 38 and 2 11, the angle between the minute hand of the clock and the hour hand of the socks is 60 degrees.
-
Analysis: The minute hand walks per minute: 360 60 = 6 degrees, the clock travels 360 12 = 30 degrees per hour, and the minute walks 30 60 = degrees is set at 5 o'clock x minute, the angle between the minute hand and the hour hand is 60 degrees At this time, the angle between the minute hand and the magic wheel 0 minutes is 6x degrees, and the angle between the hour hand and 0 is 5 * 30+ degrees, and there are two cases of the angle between the minute and the hour hand: minutes.
-
Seven fifteen minutes.
Seven and fifteen withered minutes = 29 4 hours.
The hour hand turns 29 4 30°=
The minutes are not like a mountain needle turned 15 6 = 90 °
That is, the obtuse angle of the minute and hour hands is.
-
180+30×1/12=
Between 7 o'clock and 5 o'clock is 180 degrees, and because after 5 minutes, that is, the hour hand has passed 1 12, and the hour hand has traveled 30 degrees in an hour, so it is 30 1 12
-
The number of degrees that the minute hand of the clock rotates every 5 minutes = 360 degrees 12 = 30 degrees.
The number of degrees in which the clock hand rotates every 5 minutes = 30 degrees 12 = degrees.
At 1:55 on the clock, the degree of rotation of the hour hand is: 360 degrees - 30 degrees * 11 = 30 degrees.
The degree of rotation of the minute hand is: 30 degrees + 11 * degrees = degrees.
Therefore, the angle between the hour hand and the minute hand is 30 degrees + degrees = degrees.
