Answer 2

Here, those given angles are corresponding angles.

If given corresponding angles are equal , then those lines are parallel ( l //m ) .

》 if 3x - 20 = 2x + 10, then l // m.

》 3x - 20 = 2x + 10

》 3x - 2x = 10 + 20

》 x = 30°

only if x = 30° then the lines are parallel.

Therefore, x = 30°.
