The image provided contains partially obscured text, but I will attempt to extract as much useful information as possible.

From what I can interpret, the text mentions:

• Something involving an angle and a specific trigonometric ratio.
• A mathematical expression involving $\sin(\theta)$, with a possible equation of $2 \sin(\theta) = 1$.
• A request to calculate the angle $\theta$.

Based on the partial equation $2 \sin(\theta) = 1$, we can proceed to solve for $\theta$.

Solution:

1. Divide both sides of the equation by 2: $\sin(\theta) = \frac{1}{2}$

2. The angle $\theta$ whose sine is $\frac{1}{2}$ corresponds to: $\theta = 30^\circ \text{ or } \theta = 150^\circ$ in degrees (using the principal values of sine).

Would you like further clarification or any additional details on solving trigonometric equations?

Here are some related questions:

1. What are the other trigonometric functions (cosine, tangent) for these angles?
2. How do we find angles in radians from sine values?
3. What is the general solution for $\sin(\theta) = \frac{1}{2}$?
4. How do inverse trigonometric functions work in solving such equations?
5. How does this solution relate to unit circle concepts?

Tip: Remember that sine functions repeat every $360^\circ$ (or $2\pi$ radians), so solutions can have multiple forms!
