Question

In this fig, two lines AB and CD intersect at O . If <AOC=50°, Then <BOD and <AOD are respectively
A) 135°,50°
B) 50°,130°
C) 60°,120°
D) 40°,140°​

Answer 1

It can also be written as ∠AOC + ∠AOD = 180o By substituting the values 50o + ∠AOD = 180o ∠AOD = 180o – 50o By subtraction ∠AOD = 130o According to the figure we know that ∠AOD and ∠BOC are vertically opposite angles So we get ∠AOD = ∠BOC = 130o According to the figure we know that ∠AOC and ∠BOD are vertically opposite angles So we get ∠AOC = ∠BOD = 50

Answer 2

Step-by-step explanation:

A option is the correct because <Bod is 50 degree by vertically opposite angle hence the another one will be 135 degree plz give me thanks
