Step-by-step explanation:
As we can see x and 70° is alternate with each other so it can be name as alternative angle ....
- Alternative angle are always equal....
So .....
x = 70° ( being alternative angle )
Now....we can see that y and x is vertically opposite ....so it can be name as vertically opposite angle....
y = x ( being vertically opposite angle )
y = 70°
