To find the measure of \(\angle CBF\), we first need to understand the geometric relationships in the diagram.

### Step 1: Analyze the Diagram
The image shows a line segment \(CE\) with the points \(C\), \(D\), and \(E\) marked on it, where:
- \(CD = 1\) unit,
- \(DE = x + 11\) units,
- \(CE = 2x + 12\) units.

The relationship \(CE = CD + DE\) should hold, because \(D\) lies between \(C\) and \(E\).

### Step 2: Set Up the Equation
We have the entire length of \(CE\) as \(2x + 12\), and the sum of the segments \(CD\) and \(DE\) should equal this:
\[
CD + DE = CE
\]
\[
1 + (x + 11) = 2x + 12
\]

### Step 3: Solve for \(x\)
Simplify the equation:
\[
1 + x + 11 = 2x + 12
\]
\[
x + 12 = 2x + 12
\]
Subtract \(x\) from both sides:
\[
12 = x + 12
\]
Subtract 12 from both sides:
\[
x = 0
\]

### Step 4: Calculate the Segment Lengths
Substitute \(x = 0\) back into the expressions for the segment lengths:
- \(DE = x + 11 = 0 + 11 = 11\) units,
- \(CE = 2x + 12 = 2(0) + 12 = 12\) units.

Now, \(CD = 1\) unit and \(DE = 11\) units, giving \(CE = CD + DE = 1 + 11 = 12\) units, which is consistent with the value of \(CE\).

### Step 5: Determine the Measure of \(\angle CBF\)
The problem does not explicitly define point \(B\) or provide additional information directly linked to an angle \(\angle CBF\) in the given diagram. It is possible the problem intended for the user to understand that the given lengths correspond to segments of a straight line, making \(\angle CBF\) a linear angle.

If \(\angle CBF\) is indeed on the straight line \(CE\), then \(\angle CBF\) is a straight angle, which measures \(180^\circ\).

### Final Answer:
\[
\angle CBF = 180^\circ
\]
