Explanation:

Step1: Identify angle relationship

The inscribed angle over arc DE is half the central angle. So $5x - 1 = \frac{98^\circ}{2}$.

Step2: Simplify the equation

Calculate $\frac{98^\circ}{2} = 49^\circ$, so $5x - 1 = 49$.

Step3: Solve for x

Add 1 to both sides: $5x = 50$. Divide by 5: $x = 10$.
