Answer 2

Answer:

x = 70°

Step-by-step explanation:

In ∆, 30° + 40° + /_O = 180° (Angle Sum property)

/_O = 180° - 70° = 110°

/_LOx = /_O (Vertically Opposite Angles)

/_LOx = 110°

Since, L || m

Therefore, x + /_LOx = 180° (Co-interior Angles)

x = 180° - 110° = 70°

Hope it helps!!

Have a great day!!
