On My Way.

Hey. I hope that while you are reading this, there's no judgement. I write to express. And that's all there is to this. I hope that somewhere in this heap of words you'll find something. We're all just finding ourselves out there, but we needn't do it alone.
I wish you love.

im so smart. really.

The million dollar question is…


 


Points A (-2,3) , B (5, -1) , C (-4,-7) are the midpoints of triangle PQR. Find the coordinates of P, Q, and R.


Answer:

(XP+XQ)/2= -2

XP+XQ = -4


(XP+ XR)/2 = 5

XP+XR = 10


(XQ+XR) = -4

XQ+XR = -8



= XP = -4 - XQ

= XR = -8 – XQ

XP+XR = -8 – XQ + -4 – XQ

10 = -12 – 2XQ

XQ = -11


XP – 11 = -4

XP = -4 + 11

XP = 7


-11 + XR = -8

XR = -8 + 11

XR = 3



YP = YQ = 6

YP + YR = -2

YQ + YR = -14


YP = 6 – YQ

YR = -14 – YQ

YP + YR = 6 – YQ – 14 –YQ

-2 = -8 – 2YQ

6 = -2YQ

YQ = -3


YP – 3 = 6

YP = 6 + 3

YP = 9


9 + YR = -2

YP = -11


ANSWER : P( 7, 9 ) , Q ( -11, -3 ) , R ( 3, 11 )


 


Wait. There’s more.


Time taken for the stupidity of nianci to figure this out is :

1 hour and 30 minutes.


Im such a smart person. =D
