Answer:

Step-by-step explanation:
in this circle, BC is the diameter,
hence, BCA is a semicircle,
and we know that, angle subtended by a semicircle at any point inside the semicircle is 90°,
therefore by angle sum property of triangles, we have
in ΔABC
∠A + ∠B + ∠C = 180°
=> 90° + 50° + ∠C = 180°
=> ∠C = 180° - 140°
=> ∠C = 40°
