Question

this question is from lesson parallel lines

Answer 1

angle y is 70degrees as vertically opposite angle of 110degree will also be 110 degree and angle just beside will be 70degrees and angle corresponding to it will be 70 and there is a parallelogram formed so the opposite angle will be equal....so 70=y

now, x=50 as the fig forms a huge triangle. x={180-y-50}
=x=50...

and z will be equal to x as it is corresponding angle..=50 degrees
