A
D​

Answer 1

Answer:

sir fig. toh dete toh Acha hota pehla fig. do toh answer milega kal tak

Answer 2

I have taken Angle x= angle AOC , Angle y=Angle AOD and angle z = Angle BOD

angle BOC =63°... (Given)

Angle BOC +Angle AOC =180° ...(Linear pair )

63°+AOC =180°

Angle x =Angle AOC=117°

Angle BOC =63° ...(Given)

Angle BOC= Angle AOD

... ( Vertically opposite Angles)

Angle y= Angle AOD = 63°

Angle BOC=63° ...(Given)

angle BOC +Angle BOD =180°

63° + Angle BOD =180°

Angle z= Angle BOD =117°

There are 2 methods

1* U can take Linear Pair

2* U can take vertically opposite angles

( I am using Variation

U can use one method 2 times )
