Question

Please explain it nicely.​

Answer 1

Answer:

125+e=180(linear pair)

e=180-125=55

f=e=55(vertically opposite angle)

f=a=55(alternative interior angle)

55(a)+d=180(linear pair)

d=180-55=125

a=c=55(vertically opposite angle)

d=b=125(vertically opposite angle)

Therefore, a=55,b=125,c=55,d=125,e=55 and f=55.
