Question

how to find out the answers please tell?​

Answer 1

Answer:

since p||q and transversal l intersect them

a+60°=180° (co-interior angles)

a=180°-60°

a=120° Ans

again, if l||mand transversal q intersect them

then

a=d ( alternate exterior angles)

d=120° Ans

now

b+d = 180° (linear pair angles)

b = 180°-120°

b = 60° Ans

now,line m and q intersect each other then

b=c ( vertically opposite angles)

c= 60° Ans
