The image shows a unit circle with point \( A \) on the circumference at an angle of \( 0^\circ \). The point \( A \) lies on the positive \( x \)-axis, directly to the right of the origin.

In the unit circle, a point on the circumference at \( 0^\circ \) corresponds to the coordinate \( (1, 0) \), meaning the \( x \)-coordinate of point \( A \) is:

\[
x = 1
\]
