Identify the geometric shapes and any given measurements or labels in the image.

Analysis of Geometric Shapes and Labels:

• A triangle is depicted.
• The vertices are labeled as A, B, and potentially another vertex at the top, which appears to be labeled with a '1' or 'R'.
• Side lengths or distances are indicated: a segment from A to a point on the base appears to be labeled '14'. Another segment from a point on the base to vertex C appears to be labeled '9'.
• Angles are marked: An angle at vertex A is marked as 45 degrees. An angle on the base near vertex C is marked as 45 degrees. An angle at the top vertex appears to be marked as 10 degrees or 40 degrees.
• There are also handwritten mathematical expressions and questions to the right and below the triangle:
• 'AC = ?'
• 'cos'
• '-30'
• 'AC'
• 'AB = ?'
• 'BC = ?'
• '(AC) = ?'
• '> a√2'
