Question
![On this educational webpage, we delve into the analysis of angles within the unit circle. This content is particularly pertinent for students studying trigonometry or precalculus.
### Understanding the Unit Circle
#### Problem Statement:
The graph below illustrates an angle \( A = \frac{2\pi}{3} \) within the unit circle.
##### Diagram Breakdown:
- **Unit Circle**: A circle with a radius of 1, centered at the origin (0,0).
- **Angle \( A \)**: The angle in question is \( 2\pi/3 \) radians, positioned within the circle.
- **Right Triangle**: A right triangle is formed inside the circle, intersecting the circumference and showcasing the trigonometric properties.
###### Diagram Explanation:
The unit circle diagram prominently features:
- **Angle \( A \)** (marked inside the circle as \( A = 2\pi/3 \)).
- **OPP**: The length of the opposite side (colored red).
- **ADJ**: The length of the adjacent side (colored blue).
- **Hypotenuse**: The radius of the circle (which is always 1 in a unit circle).
##### Calculation Prompt:
The task requires finding the exact values (without rounding) for the adjacent and opposite sides of the triangle formed by the angle within the unit circle.
###### Interactive Inputs:
- **ADJ** = [Input Box for Adjacent Side]
- **OPP** = [Input Box for Opposite Side]
