Question
In the figure shown, line j is parallel to line 
and line 
is parallel to line 
. What is the value of x ?
- 40
- 60
- 80
- 100
The correct answer is: 40
Parallel lines are lines that always stay the same distance apart and never meet. A transversal is a line that crosses two or more other lines.
Step-by-step solution:-
i. In the given diagram, lines j & k are parallel to each other and line m is the transversal.
∴ the angle between lines k & m is congruent to the angle between j & m (i.e. 40°) ----------- (Corresponding angles)
ii. In the given diagram, lines l & m are parallel to each other and line k is the transversal.
∴ the angle between lines m & p is congruent to the angle between p & l (i.e. 40°) --------- (Alternate interior angles)
Final Answer:-
Option A i.e. 40 is the correct answer.
