If angle between two radii of a circle is 130°, the angle between the tangents at the ends of the radii is
A. 90°
B. 50°
C. 70°
D. 40°
Answer:B
If angle between two radii of a circle is 130°, the angle between the tangents at the ends of the radii is
A. 90° B. 50° C. 70° D. 40°
Explanation: We know that the sum of the angle between two radii of a circle and the angle between the tangents at the ends of the radii is 180°.
