Question

what is the value of y?​

Answer 1

Hello mate ✋✋

Here's Ur solution :

#Angle 1 = x

#Angle 2 = 2x ( y = 2x )

#Now we know that x + 2x = 180°

( linear pair )

#3x = 180°

#x = 180°÷3

#x = 60°

#Angle 2 i.e. y = 2 × 60° = 120°

Answer ✔✔ = 120°

Hope it help u ✌✌

Answer 2

HERE IS YOUR ANSWER MATE:

_______________________________

GIVEN: 2x = y------------------(1)

FROM THE FIGURE: x + y = 180° [ linear pair property ]

=> x + y = 180°

=> x + 2x = 180° [ substituting from (1)]

=> 3x = 180°

=> x = 180°÷3

=> x = 60°

putting x=60° in (1)

60° + y = 180°

=> y = 180° - 60°

=> y = 120°

HENCE y = 120°
