Question

In the following figure, l || m and p || q . find the value of a,b,c and d​

Answer 1

Answer:

a=120° and b=30°.... okkk????

Answer 2

If p II q and l is transversal,

60° + a = 180 (Co - Interior Angles)

a = 120°

if L II M , p is Transversal,

Angle a = Angle d ( Alternate Exterior Angles )

d = 120°

Now m is a straight line ,

d + b = 180

b = 60°

and b = c (Vertically Opposite Angles)

=> c = 60°
