Question

in the given figure two straight lines intersect at point o if angle p o s is equal to 45 degree then angle q o r is equal to​

Answer 1

Step-by-step explanation:

Here we are given that POS is a straight line.

∠POQ+∠QOR+∠ROS=180

∘

(straight angle)

⇒60

∘

+5x−20

∘

+40

∘

=180

∘

⇒5x+80

∘

=180

∘

⇒5x=100

∘

⇒x=20

∘

∠QOR=5x−20

∘

=5×20

∘

−20

∘

=80

Answer 2

Answer:

angle QOR = 45 degree( vertically opposite angle)
