प्रश्न

In the given figure, the directed lines are parallel to each other. Find the unknown angles.

बेरीज

उत्तर

From 0, draw a line parallel to the given parallel lines

∴ ∠1 = 50° .......(alternate angles)

∠2 = 40°

∴ b = ∠1 + ∠2 = 50° + 40° = 90°

But a + b = 360° ........(angles at a point)

∴ a + 90° = 360° 

⇒ a = 360°− 90° = 270°

Hence a = 270°, b = 90°
