Answer 2

Answer:

Step-by-step explanation:

in line m the other side of transversal is 70°  [alternate angles]

so the other side would be 180-70=110           [linear pair]

then vertically opp. angles are equal so the opp. angle would be 110°

as it forms a triangle 110+30+x=180               [triangle sum property]

140+x=180

x=180-140=40°
