The value of x is 20°

Explanation:

Since AB || CD, ∠ LEF = ∠ EGH

∴ ∠ EGH = 85°

Here, ∠ EGH + ∠ MGH = 180°

⇒ 85° + ∠ MGH = 180°

⇒ ∠ MGH = 180° - 85°

⇒ ∠ MGH = 95°

Again, ∠ MHC + ∠ MHG = 180°

⇒ 115° + ∠ MHG = 180°

⇒ ∠ MHG = 180° - 115°

⇒ ∠ MHG = 65°

From Δ MGH, we get

∠ MGH + ∠ MHG + ∠ GMH = 180°

⇒ 95° + 65° + x° = 180°

⇒ x° = 180° - 95° - 65°

⇒ x° = 180° - 160°

⇒ x° = 20°
