The image shows a question asking for the value of the angle marked with a "2" in the diagram. From the image, we can see the following details:

- The figure depicts two intersecting straight lines.
- One of the angles is marked as \( 89^\circ \), adjacent to the angle marked with "2."

Since the two lines form a pair of adjacent angles and are straight, the sum of angles on a straight line is always \( 180^\circ \). Therefore, to find the angle marked "2", we can subtract \( 89^\circ \) from \( 180^\circ \):

\[
\text{Angle marked with "2"} = 180^\circ - 89^\circ = 91^\circ
\]

Thus, the angle marked with a "2" is \( 91^\circ \).

Would you like further details on this, or do you have any additional questions?

Here are five related questions for practice:
1. What is the sum of angles at a point where two lines intersect?
2. How do you calculate supplementary angles?
3. If one angle is \(120^\circ\), what is the adjacent angle on a straight line?
4. What is the difference between supplementary and complementary angles?
5. How do you find an unknown angle in a triangle?

**Tip**: When solving problems involving intersecting lines, remember that opposite angles are always equal, and adjacent angles on a straight line add up to \( 180^\circ \).

What is the value of the angle marked with a 2 in the given image?

Learn how to find the missing angle when two angles on a straight line are given. In this example, we calculate the angle marked '2' by subtracting the known angle (89°) from 180°. Suitable for students in Grades 6-8 studying geometry and angles.
