Answer:
correct option is c) 5
Step-by-step explanation:
In this diagram PA is tangent of circle and PB is secant of circle
since relation between secant and tangent is mention in figure-1
so, we have length of tangent AP = 6 and PE= 4
Now, put the given values in formula C² = E . ( A + E )
6² = 4 . ( A + 4 )
36 = 4 . A + 16
subtract 16 from both sides in above expression,
36 - 16 = 4 . A + 16 - 16
20 = 4A
divide both the sides by 4 in above expression,
5 = A
hence , length of BE is 5
Therefore, correct option is c) 5
