I see that you've uploaded a photo of a worksheet. Let me take a closer look at the content and provide assistance.

The worksheet contains the following exercises:

1. Question 2.2:

   • It involves a figure showing intersecting lines with labeled angles.
   • The task is to "Find the value of the unknown variable" by giving reasons for the answer. There are spaces for "Statement" and "Reason."

2. Question 2.3:

   • It also involves intersecting lines with a similar format where the unknown variable must be found, and reasons must be provided.

I will now assist you with solving these problems based on the angles and relationships involved. However, it seems like the angle measures or specific labels for angles (variables) are not entirely visible, so could you confirm the variables or provide some further details on any labels or values given for the angles?

Once I have that, I can help you step-by-step.

Feel free to ask any questions about the exercises!

1. How do you identify corresponding angles in parallel lines?
2. What is the sum of angles on a straight line?
3. Can vertically opposite angles help solve these problems?
4. What theorem can you use when two angles form a linear pair?
5. What is the sum of the interior angles of a triangle?

Tip: Always remember that the sum of the angles around a point is 360°.
