Question

please solve with full solution ​

Answer 1

Answer:

to prove that it is parallel

Answer 2

Answer:

In a) l || to m

because co-interior angles are supplementary(180)

(I.e) 110+70=180

In b) l || to m

as x = 112

since mn is a line angles are supplementary

so 68+112=180

x angle is equal to right side angle

(I.e) both the angles are same so they are interior opposite angles

Therefore l || to m.
