1. Note that the angle \( y \) subtended at the center \( O \) is given by

y = 70^\circ .

For a circle, the angle subtended at the center is twice the angle subtended at the circumference.

2. Therefore, the angle \( \angle X \) at the circumference is

\angle X = \frac{y}{2} = \frac{70^\circ}{2} = 35^\circ .

Answer:

\angle X = 35^\circ

For a circle, the angle subtended at the center is twice the angle subtended at the circumference.

2. Therefore, the angle \( \angle X \) at the circumference is
