In the given figure, the length of PB is ___ .
In the figure given below, PAB is a secant and PR is a tangent to the circle. If PA : AB = 1 : 8, and PR = 15 cm, find the length of PB.
The Line Segment AB with a Point P on it is given in the figure as :
If AP : PB = 4 : 7 and Length of AP = 20 cm, Find the Length of the Line Segment AB.
If AP : AB = 4 : 11 and Length of Line Segment PB = 14 cm, find the Length of AP.
