To solve this problem, we need to determine the minimum length of the cable, which involves basic trigonometry.

### Information from the Image:
- The height from point A (measuring point) is 1.5 meters.
- The height from point B (pole) is 2.75 meters.
- The angle between the line connecting the two points and the horizontal is \(14.5^\circ\).

This forms a right triangle where:
- The vertical difference in height is \(2.75 - 1.5 = 1.25\) meters.
- The horizontal distance (which we want to calculate) and the total cable length (the hypotenuse of the triangle) are unknowns.

### Steps:
1. **Angle and height difference**: The angle given (\(14.5^\circ\)) and the height difference (\(1.25\) meters) will help us calculate the horizontal distance using the tangent function.
   \[
   \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}
   \]
   \[
   \tan(14.5^\circ) = \frac{1.25}{d_{\text{horizontal}}}
   \]
   Solve for \(d_{\text{horizontal}}\).

2. **Cable length**: Once the horizontal distance is calculated, we can find the hypotenuse (cable length) using the Pythagorean theorem:
   \[
   L_{\text{cable}} = \sqrt{d_{\text{horizontal}}^2 + 1.25^2}
   \]

Let me calculate this for you.The horizontal distance between points A and B is approximately 4.99 meters.

Now let's compute the total length of the cable when considering the slanted angle over the entire setup. Since we were given the vertical and horizontal distances, we apply the Pythagorean theorem again using the difference in height and total horizontal distance.

Let me continue.It appears I had initially computed only the horizontal distance and vertical difference but did not consider the overall problem setup.

Let me correct that and solve for the total cable length using the proper approach.

I'll correct the analysis and solve the length fully from scratch.It seems my method didn't account for the structure of the problem correctly. I'll now re-clarify the variables and steps.
