Answer:

B. x = 20, y = 128

Step-by-step explanation:

( 3x - 8 ) and ( 2x + 12 ) are vertically opposite angles.

Vertically opposite angles are equal.

3x - 8 = 2x + 12

3x - 2x = 12 + 8

x = 20

( 3x - 8 ) + y = 180 ( Reason : Linear pair )

3 ( 20 ) - 8 + y = 180

60 - 8 + y = 180

52 + y = 180

y = 180 - 52

y = 128
