Step-by-step explanation:

Answer: x= one hundred three degrees(forms a linear pair with u). y= 77 degrees ( vertically opposite to u). z=x (vertically opposite angles).

Answer:

x= one hundred three degrees(forms a linear pair with u)

y= 77 degrees ( vertically opposite to u)

z=x (vertically opposite angles)

Answer:

since u is 77° ,y =77°(vertically opposite angles are equal)

y+x=180° ( linear pair)

x= 180-77

x= 103°

x=z= 103°( vertically opposite angles are equal)
