Question

If the angle between two radii of a circle is 130°, then the angle between the tangents at the ends of the radii is ______

विकल्प

• 90°

• 50°

• 70°

• 40°

Answer 1

If the angle between two radii of a circle is 130°, then the angle between the tangents at the ends of the radii is 50°.

Explanation:

If the angle between two radii of a circle is 130º, then the angle between tangents is 180º - 130º = 50º. (By the properties of circles and tangents)
