text: ## Elementary Geometry for College Students (7th Edition)
  
  $DF = 6\sqrt 3 \approx 10.39$ $DE= 6$
  By the given Figure $\angle F= 30^{\circ}$ So remaining $\angle F= 60^{\circ}$ FE= 12 given Now by Theorem 5.5.2 / (30-60-90 Theorem) $DF = 6\sqrt 3 \approx 10.39$ $DE= 6$
explanation: The text extract appears to be a solution or explanation to a geometry problem involving a 30-60-90 triangle. It provides the lengths of the sides and the angles, and uses the 30-60-90 theorem to justify the calculations. The extract does not contain a question but rather a detailed solution.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
