In the given image, there are diagrams related to geometry. Can you identify the type of triangles and any given angles or properties?

Analysis of Geometric Diagrams:

• There are at least three right-angled triangles depicted on the green board.
• The first triangle (labeled '1b') has an angle marked as 18 degrees. Below it, text indicates 'CH-высота' (CH-height) and angles '
• The second triangle (labeled '2b') has an angle marked as 22 degrees. Below it, text indicates 'CH-высота' (CH-height) and an angle '
• A third triangle is partially visible on the right, with labels '(1)' and '(2)' associated with it.
• The triangles appear to be right-angled at point H, with C as the apex and AB as the base.

Note: The specific mathematical problem being solved is not fully discernible without additional context or clearer text, but it involves calculations within right-angled triangles using given angles and height properties.
