In the figure PQ || RS, find the value of x.
ki77a [65]

The value of x in the figure is 125°

 And the right option is (D) 125°

To solve the problem, we use the formular for the sum of the interior angle of a polygon.

(n-2)180°

  • When a vertical line is drawn to touch point Q and S, it becomes a pentagon.
  • Pentagon: A pentagon is a polygon with 5 sides
  • The sum of the angle in a pentagon is

         (5-2)180 = 540

  • From the figure,

     ∠P+∠T+∠R+∠Q+∠S = 540°

       35+200+x+90+90 = 540

        415+x = 540

         x = 540-415

         x = 125

Hence the value of x in the figure is 125°

And the right option is (D) 125°
