Question

do the solution of 2nd

Answer 1

2.
a.
x=120 degree ( Vertically opposite angles are equal)
y=120 degrer ( corresponding angles are equal)
y+z=180 (linear pair angles)
120+z=180......(y=120)
z=180-120
z=60 degree



b.
x=105 degree......(vetrically opposite angles are equal)
y=x=105 degree........(corresponding angles)
y=105

z=y=105.......(vertically opposite angles)
z=105 degree


c.
z=40......(corresponding angles)

x+40=180.....(linear pair)
x=180-40
x=140

y=z=40......(vertically opposite angles)
y=40 degree


HOPE IT HELPS YOU!
