Question

In the given figure, if ∠AOB = 130 , then find ∠COD.​

Answer 1

Answer:

angle AOB + angle COD = Angle 180

130 +COD = 180

angle COD = 180-130

angle COD= 50

Answer 2

Answer:

Concept:

An angle is a figure created by 2 rays, known as the sides of the angle, that share a similar terminus, known as the angle's vertex.  Angles generated by two rays lie on the area in which the rays are contained.Angles are also generated when two planes meet. Geometrical angles are what they're called. Two convergingarcs can also define an angle, which is the angle formed by rays being tangent to the curves at their junction.

Given:

∠AOB = 130° , then  ∠COD.​

Find:

we have to find:

∠COD

Solution:

At the centre of a circle, opposite sides of a quadrilateral circumscribing it form additional angles.

then

 = ∠AOB + ∠COD = ∠180°

 = 130° +∠COD = 180°

 = ∠COD = 180°-130°

 = ∠COD = 50°

∴ the angle ∠COD = 50°
