Find the values of x and y in the given figure.

बेरीज

उत्तर


In ΔTQS, ∠T + ∠Q + ∠S = 180°  ......[Angle sum property of a triangle]

⇒ 50° + 30° + ∠1 = 180°

⇒ 80° + ∠1 = 180°

⇒ ∠1 = 180° – 80° = 100°

Now, ∠1 + x = 180°  ......[Linear pair]

⇒ 100° + x = 180° = 180° – 100°

⇒ x = 80°

In ΔTSR, x + 45° + ∠2 = 180°  ......[Angle sum property of a triangle]

⇒ ∠2 = 180° – 80° – 45° = 55°

Now, 50° + ∠2 + y = 180°

⇒ 50° + ∠2 + y = 180°  ......[Linear pair]

y = 180° – 50° – 55° = 75°
