Question

In figure if angle a o c and angle c o d equal and angle b o d is a right angle then the value of angle AOC and angle c o d are

Answer 1

Answer:

36

Step-by-step explanation:

As we can see from the figure, ∠AOC+∠COD+∠DOB=180

∘

…eqn(1)

It is given, ∠COD=90

∘

and

∠BOD

∠AOC

=

2

3

∠AOC=

2

3

∠BOD

Putting values in eqn (1), we get

⇒1.5∠BOD+90+∠BOD=180

⇒2.5∠BOD=90

⇒∠BOD=36
