Answer:
3) y=100° (opposite angles to B )
x= 180°-100°=80° ( adjacent angles )
z=80°(opposite angle to x)
4)y=80°(opposite angle to B)
x=180°-80°=100°( adjacent angles)
z=( to find z we have to first find angle C)
C=x =100°( opposite angle)
z+c=180°( Linear pair)
z=180°-C
z=180°-100°=80°
or
z=AngleB= 80°( same side of transversal)
