JEE MainMathematicsStraight Lines and Pair of Straight LinesMCQ+4 / −1
Let a be the length of a side of a square OABC with O being the origin. Its side OA makes an acute angle α\alphaα with the positive x-axis and the equations of its diagonals are (3+1)x+(3−1)y=0(\sqrt{3}+1)x+(\sqrt{3}-1)y=0(3​+1)x+(3​−1)y=0 and (3−1)x−(3+1)y+83=0(\sqrt{3}-1)x-(\sqrt{3}+1)y+8\sqrt{3}=0(3​−1)x−(3​+1)y+83​=0. Then aaa 2 is equal to :
