प्रश्न
In the given fig, find the values of x, y and z.
उत्तर
From the given figure
`∠`y = 25° [∴ Vertically opposite angles are equal]
Now
`∠`x + `∠`y = 180° [Linear pair of angles are x and y]
⇒`∠`x = 180° - 25°
⇒ `∠`x = 155°
Also
`∠`z = `∠`x = 155° [Vertically opposite angle]
`∠`y = 25°
`∠`z = `∠`z = 155°
