Question

In the above figure if PT = 6 cm, PA = 3 cm then AB equals to
పై పటములో PT = 6 cm మరియు PA = 3 cm అయిన AB విలువ
(3) 5 cm
​

Answer 1

where is the figure?

Answer 2

Answer:

Step-by-step explanation:

Given,

PT=6 cm

PA=3 cm

AB=?

According to the properties of tangent,

 If a chord and a tangent intersect externally, then the product of the lengths of the segment of the chord is equal to the square of the length of the tangent from the point of contact to the point of intersection.

so,

           $PT^{2}=PA*PB\\6^{2}=3*(PA+PB)\\ 36=3*(3+X) ( Let AB be x)$

            36=9+3x

             3x=27

             x=9

∴ AB = 9 cm
