Question

lines ab and cd intersect at o if angle boc =65° find x , y and z​

Answer 1

as angles x and BOC are vertically opposite angles

x= 65°

x + z = 180° as it is a straight line

z = 180-65

z=115°

y and z are also vertically opposite angles

so

y= z

y = 115°

Answer 2

Answer:

x=65°(Vertically opposite angles)

y=115°(linear pair with angle COB, 180-65=115)

z=115°(linear pair with angle x, 180-65=115)
