Question

please please please answer the question and step by step ​

Answer 1

1. x=60° (alternate angles)
2. y=55°(alternate angles)
3. angle 1 =angle 2 (l1|| l2, t is a transversal and alternate angles)
4. 60°+z=180°(sum of co interior angles is 180°)

therefore, z=120°

5. x=120°(corresponding angles)

6. a +60°=180°(co interior angles)

therefore, a=120°

a=c=120°(alternate angles)

c=b=120°(vertically opposite angles)

b+d =180°(linear pair)

120°+d =180°

therefore d=60°

a=120°, b=120°, c=120° & d=60°
