The corners AOB and BOC are adjacent. The OD beam is perpendicular to the BO beam and divides the BOC

The corners AOB and BOC are adjacent. The OD beam is perpendicular to the BO beam and divides the BOC angle into two angles. Find the COD angle if the AOB = 50 degrees.

The sum of adjacent angles is 180, then AOB + OBC = 180.

The desired angle COD = 180 – AOB – BOD.

By condition, the angle AOB = 50, and the angle BOD = 90, since DO is perpendicular to BO, then:

COD = 180 – 50 – 90 = 40.

Answer: The COD angle is 40.
