Question

In the following figure, find the value of ∠BOC, if points A, O and B are collinear.
With Formula.​

Answer 1

Answer:

Thus ∠BOC=x+5=35+5=40°

Step-by-step explanation:

AOB is astraight line

So ∠OAD + ∠COD + ∠BOC =180

x-10+4x-25+x+5=180

6x=180+30

6x=210

x=210/6=35

Thus ∠BOC=x+5=35+5=40°

Answer 2

Answer:

Thus ∠BOC=x+5=35+5=40°

Step-by-step explanation:

AOB is astraight line

So ∠OAD + ∠COD + ∠BOC =180

x-10+4x-25+x+5=180

6x=180+30

6x=210

x=210/6=35

Thus ∠BOC=x+5=35+5=40°
