Worked Solution
Step 1: In trapezium ABCD, AB ∥ CD. Line BC is a transversal cutting these two parallel lines.
Step 2: Angle ABC and angle BCD are co-interior angles (between the parallel lines AB and CD, on the same side of transversal BC).
Step 3: Co-interior angles between parallel lines sum to 180°: angle BCD = 180° − 75° = 105°.
Answer: 105°
Correct answer: 105°
