Question

In figure , l II m and n is a transversal such that ∠3∶ ∠8= 1:2,the,∠4 is​

Answer 1

Step-by-step explanation:

In the given figure ∠8=∠6 (vertically opposite angles)

It is given that ∠3:∠8=1:2

Therefore ∠3:∠6=1:2

And ∠3+∠6=180

o

(co-interior angle)

Now let the constant be x

Then,1x+2x=180

⇒x=60

o

Therefore ∠3=60

o

And ∠4=180

o

−60

o

=120

o

(linear pair)
