If the equation of the pair of straight lines passing through the point (1,1) one making an angle theta with the positive dirction of the x-axis and the other making the same angle with the positive direction of the y-axis is x^2-(a+2)xyy^2+a(x+y-1)=0, ane-2 then the value of sin2theta is

A pair of straight lines is passing through the point (1, 1). One of the lines makes an angle theta with the positive direction of X-axis and the other makes the same angle with the positive direction of Y-axis. If the equation of the pair of straight lines is x^(2)-(a+2)xy+y^(2)+a(x+y-1)=0,a ne-2 , then the value of theta is
