Answer 1

Answer:

a = 60°, b=30°, c=120°

Step-by-step explanation:

Here ∠AOD = ∠BOC { Vertically opposite angles }

a = ∠AOD

b+a = 90

a:b = 2:1

let a=2x, b=x

⇒a+b = 90°

⇒2x+x = 90°

⇒3x = 90°

⇒x = 30°

⇒a = 2x = 60°

⇒b = x = 30°

⇒∠AOD = a = 60°

⇒∠AOD+∠BOD = 180°

⇒60° + c = 180°

⇒c = 120°

Answer 2

Answer:

the answer is 120 degrees

Step-by-step explanation:

BOE =90

total parts divided =3

90÷3=30

2:1 = 2×30:1×30

a b

a=60

b=30

in intersecting lines opposite angles r equal

opposite angle = a

=60

straight angle AB =160

straight angle - opposite angle of a=ans

180-60 =120
