Question

two lines AB and CD intersect at a point o IF triangle AOC=54degree, find the value of all other angles

Answer 1

Answer:

∠AOC+∠AOD=180

o

By substituting the values

50

o

+∠AOD=180

o

∠AOD=180

o

−50

o

∠AOD=130

o

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

So we get

∠AOD=∠BOC=180

o

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

So we get

∠AOC+∠BOD=50
