If angle between two radii of a circle is 130º, then the angle between the tangents at the ends of the radii is:
A. 90º
B. 50º
C. 70º
D. 40º
Answer:B
If angle between two radii of a circle is 130º, then the angle between the tangents at the ends of the radii is:
A. 90º B. 50º C. 70º D. 40º
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)
