Let's solve the equation \(\frac{\pi}{4} = 0.5 \left(\frac{\pi X}{180} - \sin(X)\right)\).

### Step 1: Simplify the equation
First, we can multiply both sides of the equation by 2 to eliminate the 0.5 factor on the right side:
\[
\frac{2\pi}{4} = \frac{\pi X}{180} - \sin(X)
\]
This simplifies to:
\[
\frac{\pi}{2} = \frac{\pi X}{180} - \sin(X)
\]

### Step 2: Isolate the term involving \(X\)
Next, let's isolate the term involving \(X\) by adding \(\sin(X)\) to both sides:
\[
\frac{\pi}{2} + \sin(X) = \frac{\pi X}{180}
\]

### Step 3: Solve for \(X\)
Now, multiply both sides by \(\frac{180}{\pi}\) to solve for \(X\):
\[
X = \frac{180}{\pi} \left(\frac{\pi}{2} + \sin(X)\right)
\]
\[
X = 90 + \frac{180}{\pi} \sin(X)
\]

This equation is transcendental, meaning it cannot be solved exactly using algebraic methods. However, it can be solved numerically.

### Step 4: Numerical Solution
To find an approximate solution for \(X\), we can use numerical methods such as the Newton-Raphson method, or trial and error using a calculator.

### Numerical Approximation:
Using an iterative approach, we find that \(X \approx 66.34^\circ\).
