To find the value of \( y^\circ \) in the given image, we can use the concept that the sum of angles on a straight line is always \( 180^\circ \).

In the image:

1. The angle adjacent to \( y^\circ \) is given as \( 140^\circ \).
2. Since both angles are on a straight line, we know that:
   \[
   y^\circ + 140^\circ = 180^\circ
   \]
3. Solving for \( y^\circ \):
   \[
   y^\circ = 180^\circ - 140^\circ = 40^\circ
   \]

Thus, the value of \( y^\circ \) is \( 40^\circ \).
