Question

if the angle between two tangents of a circle is 75 degrees then find angle between radii of circle​

Answer 1

Answer:

105°

Step-by-step explanation:

Solve it by angle sum property of quadrilateral.

Answer 2

Given:

ABC = 75°

To find: AOC

Here,

OAB = OCB = 90° (The line drawn from the centre of the circle to the tangent of the circle forms 90°)

Thus,

OAB + ABC + BCO + AOC = 360° (Angles inside a quadrilateral form 360°)

90° + 75° + 90° + AOC = 360°

AOC = 360° - 255°

AOC = 105°
