It seems there was an issue with extracting the text from the image. I will try analyzing the image visually and provide you with a solution. Please give me a moment to work through the problem based on the image content.The image provided seems to contain a geometry or trigonometry problem that involves calculating distances and angles related to a building or a construction project. Let's break down the essential elements:

1. Diagram: The diagram shows a side view of a sloping surface with specific height measurements at various points.

2. Problem Context: It seems like the problem asks to calculate certain distances (possibly heights or lengths) using the given values.

If you can provide further details or clarify any text that may not be readable, I can provide a step-by-step solution based on that information. Alternatively, I can guide you through common trigonometric or geometric calculations typically required in such problems.

Would you like to provide more context or text from the image, or should I proceed with general geometric problem-solving based on the visual elements?
