Returns the angle coming out of the end of the segment in degrees.

```kcl
tangentToEnd(@tag: TagIdentifier): number
```



### Arguments

| Name | Type | Description | Required |
|----------|------|-------------|----------|
| [`tag`](/docs/kcl-std/types/std-types-tag) | [`TagIdentifier`](/docs/kcl-lang/types#TagIdentifier) | The line segment being queried by its tag | Yes |

### Returns

[`number`](/docs/kcl-std/types/std-types-number) - A number.


### Examples

```kcl
// Horizontal pill.
pillSketch = startSketchOn(XZ)
  |> startProfile(at = [0, 0])
  |> line(end = [20, 0])
  |> tangentialArc(end = [0, 10], tag = $arc1)
  |> angledLine(angle = tangentToEnd(arc1), length = 20)
  |> tangentialArc(end = [0, -10])
  |> close()

pillExtrude = extrude(pillSketch, length = 10)
```
