Question

in the given future ab is a straight line and angle boc =70 fibd the measure og angle aoc
answer is 110°​

Answer 1

Answer:

Given:∠BOD=40

∘

Since AB and CD intersects, ∠AOC=∠BOD(vertically opposite angles)

∠AOC=40

∘

Also,∠AOC+∠BOE=70

∘

⇒∠BOE=70

∘

−∠AOC=70

∘

−40

∘

=30

∘

We need to find reflex∠COE

Reflex∠COE=360

∘

−∠COE

Now, ∠AOC+∠COE+∠BOE=180

∘

⇒∠COE+(∠AOC+∠BOE)=180

∘

⇒∠COE+(40

∘

+30

∘

)=180

∘

⇒∠COE=180

∘

−70

∘

=110

∘

Reflex∠COE=360

∘

−110

∘

=250
