Question

If l ॥ m then find the value of x.

Answer 1

(i) In figure, l ॥ m

∠x = 60° (Corresponding angles)

(ii) In figure, l ॥ m

∴ ∠x = 50° (Alternate angle)

(iii) In figure, l ॥ m (Sum of internal angles = 180°)

∴ x+ 110° = 180°

∴ x = 180°- 110° = 70°

(iv) In figure, l ॥ m ∠x = 115° (External alternate angle)
