Step-by-step explanation:
figure 1)
e=f,c=a,d=b(vertically opposite angle)
e=c,b=125⁰(alternate exterior angle)
e=f=c=a
b=d=125⁰
sum of angles =360⁰
e+f(e)+125+125=360⁰
2e+250
2e=110⁰
e=55⁰
figure 2)
a=53⁰,z=27⁰,x=y(vertically opposite angle)
sum of angles =360⁰
2(53⁰+27⁰+x+y(x))=360⁰
80⁰+2x=180⁰
2x=100⁰
x=50⁰
