Find the missing coordinate.

Transcribed Image Text:The image depicts a two-dimensional Cartesian coordinate system with two points and angles marked within. Here's a detailed transcription:
1. **Coordinate Plane**:
- The diagram shows a standard Cartesian coordinate system with x-axis and y-axis intersecting at the origin (0, 0).
2. **Points**:
- There are two labeled points:
- Point \( (x, -1) \) is located in the third quadrant.
- Point \( (2, y) \) is located in the first quadrant.
3. **Vectors and Angles**:
- Two vectors emanate from the origin, connecting to the two points.
- There is an angle \(\alpha = 60^\circ\) in green, formed between the positive x-axis and the vector leading to \( (2, y) \).
- There is also an angle \(\beta = 170^\circ\) in red, formed between the negative x-axis and the vector leading to \( (x, -1) \).
This diagram illustrates the use of angles in determining the direction of vectors in a coordinate plane. Understanding these concepts is crucial in fields such as physics, engineering, and computer graphics.
