The image shows two intersecting lines, where one forms a right angle with a horizontal line, and an angle of $26^\circ$ is marked between the horizontal line and an inclined line. The angle labeled $b$ appears to be the complement of the given $26^\circ$ angle.

In this situation, the angles form a right angle. Since the sum of the angles around a point in a right triangle equals $90^\circ$, we can solve for angle $b$ using the formula: $b = 90^\circ - 26^\circ$ $b = 64^\circ$

Thus, the measure of angle $b$ is $64^\circ$.

Would you like further clarification or additional details?

Here are some related questions:

1. How would you apply the complementary angle theorem in other problems?
2. What happens if the angle is larger or smaller than $26^\circ$? How does that affect $b$?
3. Can you explain why the sum of angles in a right triangle always equals $90^\circ$?
4. What other geometric properties can we infer from this type of angle configuration?
5. How does this problem change if we are dealing with different types of triangles (e.g., obtuse)?

Tip: Complementary angles are often useful when dealing with right angles. Remember that they always add up to $90^\circ$.
