The image contains a circle with points A, B, and C on its circumference. There is a line segment AB, and a line segment from A to C. A right angle is indicated at point B. The image also shows the ratio of arc BC to arc CA is 2:5. Additionally, there are two small circles inside the larger circle, possibly representing the center or other points. There's also text that appears to be a question or a statement related to the geometry shown, and a text field labeled 'Мой ответ'. Based on the visual information and the provided text, what is the task or question being presented?

Analysis:

• The image displays a circle with points A, B, and C marked on its circumference.
• A line segment AB is drawn, and a right angle is indicated at point B with respect to a line segment originating from B and intersecting AC. This implies that the line segment from B is perpendicular to AC, or that angle ABC is a right angle.
• The ratio of the arc lengths BC to CA is given as 2:5.
• There are two small circles inside the main circle, which might represent the center of the circle or other significant points.
• The text "UBC: CA = 2:5" reinforces the arc ratio.
• The text "Мой ответ" (My answer) suggests that the user is expected to provide a solution.
• The figure labeled '1' and a horizontal line at the top might indicate a problem number or a separator.
• The question is not explicitly stated in the image, but it is implied that a geometry problem involving the circle, points, arcs, and angles needs to be solved, likely related to finding an angle, arc length, or chord length given the ratio and the right angle.

The task is to solve a geometry problem related to a circle, given specific information about arc ratios and a right angle. The exact question is not provided, but it likely involves calculating angles or lengths within the circle.
