It looks like you have a math sheet with various geometry problems. I can help explain the steps or provide further details for each one.

Would you like to focus on any specific problem from the sheet, or do you want a breakdown of each?

Here are a few questions that can help expand on the topics:

1. What is the formula for finding the area of a trapezoid?
2. How do you calculate the area of a regular hexagon?
3. Can you explain how to solve for an unknown side using the tangent function?
4. What is the process for finding the area of a circle if given the radius?
5. How would you calculate the area of a quadrilateral?

Tip: When dealing with shapes and areas, make sure you're clear on whether you're using the correct formulas for regular or irregular shapes!
