If pa=6 and pe= 4 find be
a: 9
b: 6
c: 5

 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

answer:

what is your question that you ask

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
