Answer 1

Answer:

((180-f)+b)-180=a...this is the ans.mark as brainliest

Answer 2

Answer:

i.f=b+a(ext.angle=sum of interior opp.angles)

or, a=f-b

ii.g=e+f(ext.angle property)

or, e=g-f

iii.angle AGF=e(vertically opp.angles are equal)

d=a+e(ext.angle property)

iv.angle GDC=180-g

c=e+180-g(ext.angle property)
