Question

if the given figure, l parallel m, find the values of a,b,c,d and e. give reason



​

Answer 1

As per diagram l ll m and n transversal.

We know that vertically opposite angles are equal

a=75----(1)

c=120----(2)

We also know that corresponding angles are equal.

d=c

we also know that alternate interior angles are equal.

a=b

=>a=b=110[ from (1)]

=>d=c=85[ from (2)]

d+e=180(linear pair)

e=180-85

e=95

Answer 2

so,

• a = 75°
• b = 75°
• c = 120°
• d = 120°
• e = 60°
