Question

in the following figures find the value of angle COD if angle abc is equal to 75 degree and a b is equal to CD​

Answer 1

75°

Explanation:

It is given that:

• AB and CD are chords of the circle which are equal.
• Equal chords subtends equal angles at the center of the circle.
• 
  `\because m\angle AOB = 75\degree`
• 
  `\therefore m\angle COD = 75\degree`

Answer 2

Angle AOB is given as 75 degrees.

O is the center of the circle so AO and CO are the same length. AB and CD are the same length, so angle COD would be the same as AOB

COD = 75 degrees.
