Answer 2

Answer:

please mark thank mark brilliant

Step-by-step explanation:

since when a straight line stands on another straight line the sum of the 2 adjacent angle is 180degree

given a straight line OD stands on a straight line AB

and angle AOD=114°

So angle DOB=180°-114°=66°

if angle DOB=69°

then angle AOD=180°-69°=111°
