Question
The image contains two geometric diagrams involving triangles and angles.

### Diagram 1:
- The diagram shows a triangle with one angle labeled as \(x^\circ\) and the adjacent angle labeled as \(135^\circ\). The triangle appears to be part of a larger figure, possibly indicating supplementary angles.

### Diagram 2:
- This diagram depicts an inverted isosceles triangle with a vertical dashed line from the top to the base, indicating symmetry or a possible altitude.
- The left angle adjacent to the base is marked as a right angle (\(90^\circ\)).
- The angle on the right side of the dashed line is labeled \(x^\circ\), and adjacent to it, an exterior angle of \(110^\circ\) is marked.
- Below the base, an angle inside the triangle is marked \(y^\circ\).
- The symmetry lines on the sides indicate equal angles or sides, suggesting an isosceles triangle configuration.

These diagrams suggest exploration of properties such as supplementary angles, isosceles triangle properties, and relationships between interior and exterior angles.
