You are solving a geometry problem. Use the following inputs:

Problem:
{problem}

Images:
{images}

Interpret the diagram(s), extract all geometric relationships, and compute any required values. Solve the problem internally and output **only the final answer** — no explanations, no steps, no labels, no extra text, and no surrounding punctuation or whitespace. The response must contain nothing except the answer itself (e.g., a number, expression, or short phrase).
