Step-by-step explanation:
2a=80°(corresponding angle)
a=80°/2
a=40°
b+80°=180°(linear pair)
b=180°-80°
b=100°

Answer:
a=40° and b=100°
Step-by-step explanation:
the sum of interior angles of transversal = 180°
80°+b° = 180°
b°=180°-80°
therefore b°=100°
vertically opposite angles are equal
2a°+100°=180°(linier pair)
2a°=180°-100°
2a°=80°
a°=80÷2
therefore a°=40°
