One diagonal of a square is along the line `8x-15 y=0`
and one of its vertex is (1, 2). Then the equations of the sides of the
square passing through this vertex are
`23 x+7y=9,7x+23 y=53`
`23 x-7y+9=0,7x+23 y+53=0`
`23 x-7y-9=0,7x+23 y-53=0`
none of these
A. 7x-8y+9=0, 8x+7y-22=0
B. 9x-8y+7=0.8x+9y-26=0
C. 23x-7y-9=0,7x+23y-53=0
D. none of these
