Question

find the unknown measure of the angle

Answer 1

Step-by-step explanation:

which angle do you want?

Answer 2

Answer:

e = 60 degrees (Corresponding angles are equal)

a + 60 = 180 (Exterior co-interior angles are supplementary)

a = 180 - 60

a = 120 degrees

b = a = 120 degrees (Corresponding angles are equal)

c = b = 120 degrees (Vertically opposite are equal)

d + c = 180 (Straight line angles are supplementary)

d + 120 = 180

d = 180 - 120

d = 60 degrees
