Suppose the parabola (y–k)2=4(x–h), with vertex A, passes through – InterviewSolution

1.	Suppose the parabola (y–k)2=4(x–h), with vertex A, passes through O=(0,0) and L=(0,2). Let D be an end point of the latus rectum. Let the y-axis intersect the axis of the parabola at P. Then ∠PDA is equal to
Answer» Suppose the parabola $(y - k)^{2} = 4 (x - h)$ , with vertex $A$ , passes through $O = (0, 0)$ and $L = (0, 2)$ . Let $D$ be an end point of the latus rectum. Let the $y$ -axis intersect the axis of the parabola at $P$ . Then $∠ P D A$ is equal to
