#### Question

(iii) In the given figure tangent PT = 12.5 cm and PA = 10 cm; find AB.

#### Solution

Since PAB is the secant and PT is the tangent

∴ `PT^2` = PA × PB

⇒ `12.5 ^2` = 10 × PB

⇒ PB `(12.5 ×12.5)/10` = 15.625 cm

AB = PB - PA = 15.625- 10 = 5.625 cm

Is there an error in this question or solution?
