Since AB = BC, So Angle A = Angle C.
b=40°
By A.S.P.
a + c = 140°
c + c = 140°
c = 70°
b=40°
By A.S.P.
a + c = 140°
c + c = 140°
c = 70°

hi
given , ab = bc
so the opposite angels should also be equal the,
angle(a) = angle (c) = x
angle(b) = 40
sum of angles in triangle is 180
angle(a) + angle(b) + angle(c) = 180
x + 40 + x =180
2x = 140
x = 70
angle(c) = 70
