Answer 2

Answer:

: Let the angle opposite to 110\degree110° be y.

Therefore y=110\degreey=110° (Vertically opposite angles)

\angle x+\angle y=180\degree∠x+∠y=180° (Sum of interior angle on the same side of transversal)

\angle x+110\degree=180\degree∠x+110°=180°

Therefore \angle x=10\degree-110\degree=70\degree∠x=10°−110°=70°

Thus x=70\degree70°

(ii): \angle x=110\degree∠x=110° (Pair of corresponding angles)
