## ashleyvee 2 years ago Can someone help me find the length in this problem? Its between 22 and 23.

1. ashleyvee

2. cwrw238

i'll have to checkout the theorem PK^2 = the product of the other two segments hold on a moment

3. ganeshie8

PK^2 = PS.PT

4. ashleyvee

20 times 6. or 20 plus 6 ?

5. cwrw238

right ganes has got it its times

6. ashleyvee

20*6=1200

7. cwrw238

also PK^2 = PN * PM so PN.PM = PS.PT

8. ashleyvee

22* ?= 1200

9. ashleyvee

i dont have pn

10. cwrw238

you have the wrong values PS = 20 and PT = 26

11. ashleyvee

20*26 = ?

12. ashleyvee

520

13. cwrw238

right now lets let PN = x so PM = 22 + x do u follow that?

14. ashleyvee

yeah.. but how do i get x?

15. ashleyvee

is my answer 22 or 23 is all im asking.. :/

16. cwrw238

PN . PM = x (x + 22) right

17. ashleyvee

ive wasted 18 minutes on this problem alone. im going to have to move on now. thx for trying.

18. cwrw238

well another 3 minutes and we've done it

19. cwrw238

and learning how to do it is not a waste of time...

20. ashleyvee

it should take less then 5 to do this problem. so yeah i would call it a waste. :/

21. ashleyvee

Especially since i have about 10 more problems just like this.. i cant take 20 minutes to do each. thats insane/ thanks for trying again..

22. ganeshie8

Once you know how to do it, it takes no time... how much time did u take learning walking when you're kid ? stop rushing ok...

23. cwrw238

x(x+22) = 520 x^2 + 22x - 520 = 0 x = 14.42

24. ashleyvee

Ive tried for 4 years. I just give up. Sorry for being rude. But thanks.

25. cwrw238

* 14.32
