    Note that the problem states that the outer shape is a quarter circle, information not provided in OP’s question.

    Knowing it is a quarter circle is important because it allows us to validate that the bottom-right angle is 90 degrees.

        It has to be given, otherwise there would be infinitely many solutions.

        You would need some other information to link the line segment X to the rest of the figure.
