given parabola is y^2=4ax
focus of this parabola is s(a,0)
putting s(a,0) in the given line equation x-y-a=0 we see that it satisfies the point (a-0-a=0).
so line passes through the focus of the gven parabola. hence it is focal chord and tangents at the end of focal chord are always perpendicular to each other and meet at the directrix, hence the ange between them is pi/2.
