    We are given:
    – The angle between two radii of a circle is 130°.

    Key property of tangents
    The tangents at the ends of the two radii are perpendicular to their respective radii. Therefore, the angle between the tangents is the **supplement** of the angle between the radii.

    Calculate the angle between the tangents
    The sum of the angle between the radii and the angle between the tangents is 180°. Thus:
    Angle between tangents = 180° – Angle between radii.

    Substitute the given angle between the radii:
    Angle between tangents = 180° – 130° = 50°.

  5. When two circles intersect at two distinct points, the maximum number of common tangents that can be drawn is 2.

    When two circles intersect at two distinct points, the maximum number of common tangents that can be drawn is 2. These tangents are the **external tangents**, as the circles are close enough to each other and intersect, so no internal tangents can exist.

    Explanation:
    – If two circles intersect at two points, they share a region of overlap.
    – Only two external tangents can be drawn, one on each side of the circles.
    – No internal tangents are possible because the circles are not separate or disjoint.
    This question is connected to Chapter 10 of the Class 10th NCERT Mathematics textbook, which focuses on “Circles.” Provide your response based on your comprehension of the concepts discussed in this chapter.
