Question

what is the value of y ..and dear plz explain it with steps ..thanku in abvance ​

Answer 1

Answer:

y = 30°

Step-by-step explanation:

y = x [ vertically opposite angles ]

&

3x + y + 2x = 180° [ They form a linear pair ]

⇒ 3x + 2x + x = 180

6x = 180

x = 180/6 = 30°

Therefore, x = y = 30°

Answer 2

Step-by-step explanation:

From the given figure,

y and x are vertically opposite angles

we know that vertically opposite angles are equal.

y =x..........(1)

and we know that

the angle around a point is equal to 360°

=>3x+2x+x+3x+2x+y=360°

=>3x+2x+x+3x+2x+x=360°......from(1)

=>12x=360°

=>x= 360°/12

=>x=30°

=>y= 30°

The value of y = 30°
