The eqautions of lines `L_(1) and L_(2)` are `y=mx and y=nx`, respectively. Suppose `L_(1)` makes twice as large an angle with the horizontal (measured counterclockwise from the positive x - axis) as does `L_(2)` and m = 4n, then the value of `((m^(2)+4n^(2)))/((m^(2)-6n^(2)))` is equal to (where, `n ne 0`)
