Question

in the given figure if x= 5/4 y° .find the value of AOC and BOC .​

Answer 1

Answer:

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

∘

Answer 2

Answer: the angles are 80 and 100

Step-by-step explanation: You have not given the diagram so I am assuming it to be a linear pair or a straight angle.

x + y = 180

5/4 y + y = 180

9/4 y = 180

y = 80

So, the angles are 80 and 100
