Question

solve it urgentttttt​

Answer 1

Answer:

x = 120°

y = 110°

Step-by-step explanation:

x is the exterior angle of ∆AOC

Therefore, x ° = sum of opposite interior angles.

⇒ x = 40° + 80° = 120°

Angle AOC = Angle BOD [ Vertically opposite angles ]

40° = Angle BOD.

y is the exterior angle of ∆BOD

Therefore, y = sum of opposite interior angles.

⇒ y = 40° + 70° = 110°

Answer 2

Answer:

x+y=230

Step-by-step explanation:

80+40+CAO=180

CAO=60

180-CAO=x

x=120

DOB=CAO

DOB=60

60+70+OBD=180

OBD=90

180-OBD=y

y=110

x+y=110+120

x+y=230
