Best ResponseYou've already chosen the best response.0i don't think i can give you any solid geometric reasoning here... but I'm pretty sure PO = 3 you're given this.. dw:1433140089676:dw

Best ResponseYou've already chosen the best response.0because A is the center of the circle, and AN is perpendicular to MO, it must bisect MO. therefore MN = NO dw:1433140254126:dw

Best ResponseYou've already chosen the best response.0you also know that AP and AN are equal lengths: dw:1433140308669:dw

Best ResponseYou've already chosen the best response.0For the lines RO and MO to intersect at a point on the edge of the circle, and for both of the lines to be perpendicular to AP and AN respectively, OR has to be a reflection of MO dw:1433140389665:dw

Best ResponseYou've already chosen the best response.1http://www.regentsprep.org/regents/math/geometry/gp14/circlechords.htm extending NA such that it is a radius since NA is perpendicular to chord MO, it is a perpendicular bisector. so NO= half of 6 which is 3
