On opposite side

here , XY is the perpendicular distance

now perpendicular from center will bisect the chord

AX=15

AO = 17...(radius)

apply pythagoras to find 

OX=8cm

similarly in triangle OCY

OY=15 cm

total XY = 23 cm


Now find the distance in case 2 on the same side of the centre

XY = 7cm
