If `A(5,2),B(10,12)` and `P(x,y)` is such that `(AP)/(PB) = (3)/(2)`, then then internal bisector of `/_APB` always passes through

A

`(20,32)`

B

`(8,8)`

C

`(8,-8)`

D

`(-8,-8)`

Text Solution

Verified by Experts

The correct Answer is:
B
Let internal bisector of `/_APB` meets the side AB at C. We know that `(AC)/(BC) =(AP)/(PB)`
`:. (AC)/(BC) =(3)/(2)`
`:.` coordinates of C are `((3(10)+2(5))/(3+2),(3(12)+2(2))/(3+2))` or (8,8) Hence the internal bisector of `/_APB` always passes through point (8,8)
