Respuesta :

x = 10°

y = 112°

Step-by-step explanation:

From the definition of supplementary angles,

68° + y = 180° ---> y = 180° - 68° = 112°

From the definition of vertical angles,

(4x - 2) + 30 = 68

4x - 2 = 68 - 30 = 38

4x = 40

x = 10

Answer:

y+68=180(being straight angle)

y=180-68

y=112

4x-2=30

4x=28

x=7
