Answer:
AB=BC
∠A=∠C (angles opp to equal sides are equal)
IN ΔABC,
∠C+∠B+∠A=180 (ASP)
2∠C+80=180 (∠A=∠C)
2∠C=100
∠C=50°=∠A

Step-by-step explanation:
AB=BC
therefore angle C = angle A (the angle opposite to congurent sides is congurent)
let angle C = angle A = X
angle B = 80° ( given )
therefore angle A + angle B + angle C = 180°
X+X+80°=180°
2X+80°=180°
2X=180°-80°
2X=100°
X=100°\2
X=50°
therefore angle C=50°
