Analyze the geometric figures and identify any numerical or symbolic data present.

The image contains three geometric diagrams with accompanying labels and numerical data.

Diagram 1:

• Labeled as '2)'.
• A circle with an inscribed triangle ABC.
• Angles are marked with question marks.
• An angle inside the triangle is labeled '120°'.
• A segment is labeled '93?'.
• Vertices are labeled A, B, C, and D.

Diagram 2:

• Labeled as '4)'.
• A triangle ABC with an inscribed circle.
• Segments of the triangle sides are labeled '25' and '15'.
• The sides adjacent to vertex A and C are marked with question marks.
• An equation 'P = 90' is written next to the diagram.

Diagram 3:

• Labeled as '6)'.
• A circle with an inscribed quadrilateral ABCD.
• Angles and sides within the quadrilateral are marked with question marks.

Additional text fragments include 'T', 'C', 'A', '186°', and 'B C'.
