Question

find each of the lettered angles giving reason​

Answer 1

Step-by-step explanation:

50°

d=50°.....(1)(corresponding angles)

d+c=180° ......(angles in linear pair)

50°+c=180°......(from 1)

c=180°-50°

c=130°.....(2)

b=50°......(3)(corresponding angles)

a=50°......(4)(alternate angles)
