Question

In the given figure below, decide whether l is parallel to m.

Answer 1

98 + ∠x = 180° (Linear pair)

∠x = 180° - 98° 

∠x = 82°

For l and m to be parallel to each other, the corresponding angles (∠ABC and ∠x) should be equal. However, here their measures are 72° and 82°, respectively. Hence, the lines l and m are not parallel to each other.
