To find the degree measure of the angle formed when moving clockwise from the 11 o'clock position to the 4 o'clock position on a clock face, we can start by determining the positions of each hour in degrees.
Each hour on the clock represents \(30°\) because: \[ \frac{360°}{12} = 30° \]
Now, let's find the degree positions of 11 o'clock and 4 o'clock:
-
11 o'clock: \[ 11 \times 30° = 330° \]
-
4 o'clock: \[ 4 \times 30° = 120° \]
Next, we will calculate the angle moving clockwise from 11 o'clock to 4 o'clock. Since the movement is clockwise, we can subtract:
- Start from 11 o'clock (330°).
- Move to 4 o'clock (120°).
To find the clockwise angle, we can do: \[ \text{Angle} = (360° - 330°) + 120° = 30° + 120° = 150° \]
Thus, the degree measure of the angle formed moving clockwise from 11 o'clock to 4 o'clock is \(150°\).
