This one is a little difficult.....

 

Since NA = PA....then chords  RO and MO  are equidistant from the center of the circle, A...and chords that are equidistant from the center of a circle are equal.....thus RO  = MO  = 7

 

Further....a segment drawn from the center of a circle that is perpendicular to a chord, bisects that chord

 

So  since AP is perpendicular to RO   and  AN is perpendicular to  MO.....then 

 

RP = PO  = 1/2 RO     and MN = NO = 1/2 MO

 

But PO  = 1/2 RO  and since RO = MO then PO  =  (1/2) MO 

 

Then PO  = (1/2) * 7   =  3.5

 

 

cool cool cool
