Q1 of 11 Page 11

Choose the correct alternative.

In the adjoining figure, if line a || line b and line l is a transversal then find x.



• Given: Line a || line b and line l is a transversal


• To find: Value of x.


Now from the figure we can see



∠GHB=∠CHF (∵ opposite angles are same)


⇒ ∠GHB=2x


∠AGB+∠BHG=180° (∵ (∵ Property of interior angles.)


∴ 4x+2x=180°


⇒ 6x=180°


⇒


∴ The value of x is 30°
