Angles 60°, 70° and y form a straight line.
Angle on a straight line is 180°
So to get y it will be 180°-(60°+70)
Which is equal to 180°-130°= 50°
Y= 50°
Y and x are vertically opposite angles and vertically opposite angles are equal so therefore x=y and y=50° so x is also equal to 50° or also to find x you could do the same method as the way to find y. Angles 60°, 70° and x form a straight line. So 180°- (60°+70°)= 180°-130°=50°
X=50°.
