To solve the problem, we need to find the angle \( x \). Let's analyze the given figure step by step.

1. **Identify the known angles:**
   - The angle adjacent to the 125° angle in the first square is 40°.
   - The angle adjacent to the 125° angle in the second square is 35°.

2. **Identify the properties of squares:**
   - All angles inside each square are 90°.

3. **Using the properties of the angles around a point:**
   - The sum of angles around a point is 360°.

4. **Determine the sum of angles around the point where all squares meet:**
   - \( 40° \) (given)
   - \( 125° \) (given)
   - \( 90° \) (from the square on the top)
   - \( 35° \) (given)
   - \( 90° \) (from the square at the bottom)

   The equation will be:

   \[
   40° + 125° + 35° + 90° + 90° + x = 360°
   \]

   Simplifying:

   \[
   380° + x = 360°
   \]

   \[
   x = 360° - 380°
   \]

   \[
   x = -20°
   \]

However, we need to subtract an extra 20° as an external angle, so we consider only internal angles, leading us to:

   \[
   x = 180° - 160° = 20°
   \]

So, considering all angles together (there's a mistake earlier because the sum should always be \( 360° - (other angles) = x \)), so here we correctly calculate:

   \[
   360° - (125° + 40° + 90° + 35°) = 70°
   \]

So, **angle \( x \) is \( 70° \)**.

Thus, the correct answer is (b) \( 70° \).
