Answer 2

∠K + ∠R = 180°   (adjacent angles of a parallelogram are supplementary)

⇒ 120° + ∠R = 180°

⇒ ∠R = 180° - 120° = 60°

also, ∠R = ∠SIL   (corresponding angles)

⇒ ∠SIL = 60°

also, ∠ECR = ∠L = 70°   (corresponding angles)

x + 60° + 70° = 180°   (angle sum of a triangle)

⇒ x + 130° = 180°

⇒ x = 180° - 130° = 50°
