Question

From information of angles given in figure, find out the values of x, y, z​

Answer 1

Answer:

We know that, 40

o

+x+25

o

=180

o

[Angle on straight line]

⇒65

o

+x=180

o

⇒x=180

o

−65

o

=115

o

Similarly, 40

o

+y=180

o

[Linear pair]

⇒y=180

o

−40

o

=140

o

....(1)

Also y+z=180

o

[Linear pair]

⇒140

o

+z=180

o

[From eq. (1)]

⇒z=180

o

−140

o

=40

o

Thus, x=115

o

,y=140

o

and z=40

o
