Answer 1

Answer:

a) x=70⁰ y=60⁰

b) y=80⁰ x=50⁰

Answer 2

Answer:

a)y=180-120(angles on straight line)

  y=60

x+50=120(interior opposite angles of a triangle)

  x=120-50

 x=70

b)y=80 (vertical opposite angles)

   x+80+50=180(sum of interior angles in a triangle)

    x+130=180

      x=180-130

      x=50
