Question

in the adjoining figure l//m.Find the value of the unknown angles​

Answer 1

Answer:

Step-by-step explanation:

Suppose an angle 'g' on line 'l'.

Now,

g = 135 (Vertical opposite angle)

g + a= 180 (co-interior angles)

a = 180-135

a = 45

a=c (vertical opposite angle)

c=45

a + f= 180 (alternate interior angle)

f = 180-45

f = 135

f=e (vertical opposite angle)

e=135

f + d= 180 (co-interior angles)

d = 180-135

d= 45

d=b (vertical opposite angles)

b=45
