Question

in the given figure the lines AB and
CD are intersecting at apoint 'o' angle. Aoc = 50
find angle BoD​

Answer 1

Answer:

AOC and∠AOD from a linear pair

It can also be written as

∠AOC+∠AOD=180o

By substituting the values

50o+∠AOD=180o

∠AOD=180o−50o

∠AOD=130o

According to the figure we know that ∠AOD and ∠BOC are vertically opposite angles 

So we get

∠AOD=∠BOC=180o

According to the figure we know that ∠AOC and ∠BOD are vertically opposite angles

So we get

∠AOC+∠BOD=50o
