Question

line l 1 and l 2 intersect with each other . find the value of x,y and z​

Answer 1

Answer:

As per the diagram, two lines l

1

& l

2

intersected to form two pairs of vertically opposite angles.

x=z -- (1)

u=y --(2)

From (1)

x=z=45

o

.

We also know that the sum of all the angles around a point is 360

o

x+u+z+y=360

o

⇒45+u+45+u=360

o

{∵y=u as they are vertically oppposite angles}

⇒90+2u=360

o

⇒2u=270

o

⇒u=135

o

⇒y=135

o

∴ x=45

o

,z=45

o

,u=135

o

and y=135

o

.
