Answer: 12 UNIT
Step-by-step explanation:
1. Join AD
2. ∠ ADC = 90 ° (∵ Angle substending the diameter is 90°)
3. Δ ADC is similar to ΔBAC ( ∵ ∠ADC = ∠BAC = 90° and ∠C = ∠C - common angle - AA similarity)
4. BC / AC = AC / DC
5 . ∴ AC² = BC × DC
AC² = 16 × 7
= 112
6. AB² = √(256-112)
= 144
7. AB = 12
