Two tangents are drawn from point P to a circle such that the angle between them is 80°. Find the angle between the radii drawn to the points of contact.

1. 80°
2. 100°
3. 90°
4. 110°

Correct answer: 100°

Solution

The angle between two tangents from an external point and the angle between the radii to the points of contact add up to 180°. Since the angle between tangents is 80°, the angle between the radii is 100°.
