In figure, if AOB = 125°, find the COD.


Given: AOB = 125°


To find: COD


Explanation:


As in the given figure ABCD is a quadrilateral circumscribing the circle and we know that, the opposite sides of a quadrilateral circumscribing a circle subtend supplementary angles at the center of the circle.


So, we have


AOB + COD = 180°


125° + COD = 180°


COD = 55°
