Question

find the value of x and y.Arrows show that the lines are parallel

​

Answer 1

Answer:

draw a line parallel to both the lines and passing through x and y

x=90°

y=360-x

=270°

I have to go for urgent work bro do can't explain right now..

Answer 2

1. we have to draw another parallel lint parallel to both line.
2. angle OAB=40°
3. Angle OEF=45°
4. angle COA=40°( by alternate interior angle)
5. angle OEF=45°
6. angle COE=45°
7. therefore angle AOE=45+40=85°
8. reflex of angle AOE=y
9. therefore reflex of angle AOE=360-85=275°
