similar triangles?In ,quadrilateral QRTS we have QR = 11,QS = 9 , and ST=2. Sides RQ and ST are extended past Q and S , respectively, to meet at point P. If PS=8 and PQ=5, then what is RT? I see you have graph paper. You must be plotting something #2 20130402 03:04:07
Re: similar triangles?I would say 18. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #3 20130402 03:13:07
Re: similar triangles?thanks! my teacher gives me hard hwk. I see you have graph paper. You must be plotting something #4 20130402 03:16:57
Re: similar triangles?Do you understand why the answer is 18 for the last one?

Re: similar triangles?yah i get it. you add some extra lengths to 5 and 8 and then you get similar triangles. i did not see that at first. I see you have graph paper. You must be plotting something #6 20130402 04:08:22
Re: similar triangles?Well, for the second problem, I would say the answer is 6.
