|dw:1334216398007:dw| M is mid pt of PR or QS??

  • lgbasallote
if QS = 10 then QM = 5 5^2 is 25 right?
anonymous

@lgbasallote , u r wrong.

M is mid-point of PR.

I have done the answer, shall I post it? Will u correct it?

\[\frac{\sqrt{24}+\sqrt{96}}{2}\]

Wrong again.

that is equal to PM

Cos rule i guess...what is QRM=

sorry QPM?

QPM is not given.

let midpoint of QS = A sqrt (11^2 - 5^2) = AR AR = sqrt (121-25) AR = sqrt (96) AR = 4 sqrt (6) PM + AR = PR + MA PM = PR/2 PR/2 + 4 sqrt 6 = PR + MA lol =)))

so v can find it using sin x = 5/7
anonymous
  • anonymous
Shall I say how I did? Please. then u will check and rectify me.
anonymous
  • anonymous
ok?

yeah aadarsh post i am not in the patient mood to type such long replies right now.
anonymous
  • anonymous
Just a minute.
anonymous
  • anonymous
answer is 31 = QM^2= 32
anonymous
  • anonymous
31*

How u did @thushananth01 ? Can u say the reason please? U r absolutely right.
anonymous

ok first find the full length of PR u can do this first by using pythagoras theorom then u have to add both and divide by 2 to get the midpoint as i gve previous with the radical..that was the length from P to M now we know PM and PQ plus the angle QPM v can find using the sin rule then i got the angle as 45.6 then finally the cose rule\[p^{2}= q^{2} + m^{2} - 2qm (cos P)\] \[7^{2}+7.35^{2} - 2 \times 7 \times 7.35 \cos 45.6 = p^{2}\rightarrow QM^2\]
anonymous
  • anonymous
\[\frac{\sqrt{24} +\sqrt{96}}{2}\rightarrow PM\]
