Question

19. In the given figure, straight lines AB and CD
intersect at O. IF <AOC + <BOD = 130° then
<AOD = ?​

Answer 1

Answer:

<AOD=115

Step-by-step explanation:

angle AOC and angle BOD are vertically opposite so equal

so 130 by 2 equals 65

then angle AOC and angle AOD is linear pair

so angle AOD = 180-65=115
