PA and PB are tangent to the circle at A and B respectively and the chord BC is parallel to tangent PA.If AC=6 cm and lenght of tangent AP is 9 cm.Then what is the length of the chord BC.
Read Solution (Total 5)
-
- PA = PB = 9 cm ( Length of tangents from an external point)
Angle PAB = Angle ABC ( alternate angles PA !! BC)
AC = AB = 6 cm
Triangles PAB and ACB are Isoscelles and sre similar triangles
( They are equiangular)
Taking the ratios of respective sides
BC/AB = AC/PB
BC/6 = 6/9
BC = 4 cm - 8 years agoHelpfull: Yes(4) No(0)
- plz give ans .how to solve this ?

- 9.....
because PA opposite side is BC and PB opposite side is AC which forms a square.
So ans is 9
