Question

In the adjoining figure find a, b, c and d of l//m
​

Answer 1

Answer:

a=120

b=65

c=65

d=65

Step-by-step explanation:

since l || m

<a = 120° (vertically opposite angles)

&

<b = 65° (VOA)

<c=65° (angle besides <c will be 120° corrosponding angles therefore they make a linear pair )

<d =65° (same theory as <c)

plz mark my answer as brainiliest

Answer 2

Step-by-step explanation:

a=120°(vertically opposite angle)

b=65°(vertically opposite angle)

b=d(adjacent angles)

=d=65°

120°+e=180°(intersecting lines)

180-120=60°

c=60°(vertically opposite angle)
