Proof Question I spent 2 days already
Posted:
Jul 28, 2008 3:02 AM


hey teachers and experts
I have this extreme problem which took me 2 days to look over
There are 3 proof parts, a and b are easy to prove anyway but I am stuck with problem c
Please take a look at this original problem http://i64.photobucket.com/albums/h187/jwxie/untitled6.jpg
The givens are the following RS and QT are the altitude of Triangle PQR; PQ = RU
I did part A using "AA ~ AA"
Since altitude makes a right angle, so <QSU , <UTR are both right angles then next we have the vertex angles...
Part B I used AAS =~ AAS
<PTQ = <UTR (Right angle) <URT = <SQU (already proven from part A) and side is the given
Now, part C is the problem The question is
FIND < PRQ (angle)
here what I did for 2 days http://i64.photobucket.com/albums/h187/jwxie/untitled5.jpg
I tried to setup a 3variable equations 360 = 180+ (180y) + z z = 90+x x = 90y
but I always get the same answer 0 = 0 which means this is not the equation to solve for either unknown variable
Would someone please help me to find it?
