The image appears to contain a question with a diagram, where the task is to calculate the length of a side, likely using trigonometry or geometry based on angles and dimensions. Since the image is blurry, I cannot clearly read the text and exact values.

If you could provide the specific numbers or additional text details from the image, I can offer a step-by-step solution.

Alternatively, I can help guide you based on what seems to be a triangle diagram with an angle and distances involved. Let me know how you would prefer to proceed!
