Answer 2

Answer:

(i)Here ∠HGB=∠AGE(vertically opposite angles)

∠HGB=110 ∘

Now, for parallel lines l and m, with transversal t.

∠HGB+∠GHD=180 ∘

(Angles on the same side of the transversal are supplementary)

110 ∘ +∠GHD=180 ∘

∠GHD=180 ∘ −110 ∘

=70 ∘

(ii)For parallel lines l and m with transversal a

∠AIE=∠CJI (corresponding angles)

⇒x=100 ∘
