The image you uploaded appears to be a problem involving trigonometry, likely dealing with angles of elevation or depression and distances.

To help you solve this, I need to analyze the image content carefully. Let me extract the problem details and proceed with a solution.

Extracted Problem Details:

1. Visual Description: The image shows a right triangle, with one angle at the base of a tower or a building. A line of sight seems to be drawn from a certain point on the ground to the top of the tower, forming the hypotenuse of the triangle.

2. Text Description:

   • The problem is related to a lighthouse and involves calculating a certain distance or angle using trigonometry.

Steps to Solve:

1. Identify the Known Values: From the image, determine the given lengths or angles.
2. Use Trigonometric Ratios: Based on the given information, use appropriate trigonometric ratios (sine, cosine, tangent) to find the unknown length or angle.
3. Apply the Formula: Plug in the known values into the formula and solve for the unknown.
4. Check for Units: Ensure that the final answer is in the correct units.

Since I cannot directly extract the entire text, I will need a brief description of the specific details or any numbers mentioned in the problem (e.g., the height of the tower, distance from the point to the tower, angles given).

Please provide those details, or if they are visible, I can proceed to solve the problem from the current information. Would you like to describe the problem further or have me make some assumptions to proceed?
