  • a)
    30°
  • b)
    40°

    50°
  • d)
    60°
Correct answer is option 'B'. Can you explain this answer?

In ΔABC, ∠ACB = 90°
∴ ∠ACB + ∠ACD = 
90°+ 50° = 140°
As angle mode by triangle
in semicircle is equal to 90°
∴ In quad. ABCD, ∠BAD + ∠BCD = 180° (angle of opp. pair of quad is equal to 180°)
∠BAD =180° - 140° = 40°
