Best ResponseYou've already chosen the best response.0dw:1358257312264:dw " in the figure, given that point P= point Q . AB=CD , AB=24, and PX=p . what is the length of the given radius Q?

Best ResponseYou've already chosen the best response.0sorry Q is where P is at on the first circle . you see how i put d twice ? well Q is where P is . get it ?

Best ResponseYou've already chosen the best response.0hmm thought so....so u need to find out the radius QY?

Best ResponseYou've already chosen the best response.0can u check the question again? i didnt exactly get what u meant by point P = point Q....how can two points be equal?

Best ResponseYou've already chosen the best response.0okay how about i just give you the answer ? , so you can understand how to get it ? ... its 15

Best ResponseYou've already chosen the best response.0that'd be only possible if any of the following angles are given. dw:1358258436102:dw

Best ResponseYou've already chosen the best response.0sure...but dont u think we should finish solving it first?

Best ResponseYou've already chosen the best response.0what was the given length of the segment that i showed in my last picture??

Best ResponseYou've already chosen the best response.0lol and u said PX=p :P :P ok here's the basic theorem, lets say you draw a line from the center of a circle to any chord of the circle, and the angle formed becomes 90 degree dw:1358259896480:dw in that case, the point where the line touches the chord will bisect it, so in ur first picture, since AB=24, <x=90, then AX=XB=12 (bisected, halved) and as both the circles are similar, same goes for circle Q too. now, its simple pythagorean theorem dw:1358260014603:dw is it clear now?

Best ResponseYou've already chosen the best response.0yay and yes . ready for the next one?

Best ResponseYou've already chosen the best response.0okay the next one is the picture i sunt you

Best ResponseYou've already chosen the best response.0ok let me explain the second one. as you can see, ND=MB=26 is the radius for both the circles. QD is already given (you dont need to halve the chord like u did before, QD is already half), also. QD=LB now use pythagorean theorem to find out LM dw:1358260511366:dw
