Question

find the values of x and y

1. x=129, y=51
2. x=51, y=129
3. x=66, y=17
4, x=17, y=66

Answer 1

Heya...
Here is your answer ----

________________________
=> 2x-3 = 129 (vertically opposite angle)

=> 2x = 129+3

=> 2x = 132

=> x = 132÷2

=> x = 66°
________________________

=> (2x-3) + 3y = 180 (linear pair)

=> 2×66-3 + 3y = 180

=> 132-3 + 3y = 180

=> 129 + 3y = 180

=> 3y = 180 - 129

=> 3y = 51

=> y = 51÷3

=> y = 17°
________________________

Option 3. x=66°, y=17° is correct.

HOPE IT HELPS...!!

Answer 2

heya!!

Answer will be => Option 3. x=66°, y=17°

Solution -

2x-3 = 129 ( VOA)

=> 2x = 129+3

=> 2x = 132

=> x = 132 ÷ 2

=> x = 66°

Next,

=> (2x-3) + 3y = 180 (linear pair)

=> 2×66-3 + 3y = 180

=> 132-3 + 3y = 180

=> 129 + 3y = 180

=> 3y = 180 - 129

=> 3y = 51

=> y = 51 ÷ 3

=> y = 17°

Hope it helps!!
