Analyze the image and identify geometric shapes and any associated values or variables.

Analysis of Geometric Shapes:

• The image displays two right-angled triangles, drawn on a grid background.
• Top Triangle:
  • Features a right angle symbol.
  • One acute angle is marked with an arc and labeled with 'x'.
  • Another angle is marked with arcs and labeled with '50°'.
• Bottom Triangle:
  • Features a right angle symbol.
  • One acute angle is marked with an arc and labeled with 'x'.
  • Another angle is marked with arcs and labeled with '50°'.
• There are also some handwritten characters to the right of the triangles, which appear to be 'C' and 'Le', but their context is unclear without further information.
