Question

in the given fig pos is a line then qor is​

Answer 1

Answer:

Step-by-step explanation:

If this is the given Fig. then here is the answer and the solution.  

In the given figure, POS is a line, find the measure of ∠QOR.

   

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∘

So the measure of ∠QOR is 80∘.
