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
