The value of PB from the given figure
Answer to Problem 19WE
The value of PB is 4
Explanation of Solution
Given information:
It is given PD=5, CD=7, AB=11 and a figure,
Let PB = x
When a secant segment and a tangent segments are drawn to a
Therefore, from the given figure
Also
Comparing and solving both the equations
This gives x = 4 or x = -15
Since length is never negative. So we reject x = -15
Therefore the value of PB = 4
