no spamming pl​

Answer 1

Answer:

a is 80 by opposite angle

Step-by-step explanation:

c and b are 100

Answer 2

Step-by-step explanation:

angle a =80 degrees opposite angles)

(vertically since angle a = 80 degrees,

another angle of c ( the remaining angle of c) = 180-c = 80 degrees =

(alternate interior angles)

hence c=180-80 = 100

since angle c=100 , angle b=100 (corresponding angles)
