Question

In the given figure, if lines l and m are parallel lines, then find the value of x.​

Answer 1

Answer:

in the given figure x = 40 degrees

Answer 2

Step-by-step explanation:

Exterior angle of the traingle= 70° (As they form corresponding angles, l || m )

Now, we know,

Sum of non-adjacent interior angles is equal to exterior angle in a traingle( Exterior angle theorem).

x + 30° = 70°

=> x= 40°
