AB is a vertical pole and C is its mid point. The end A is on the level ground and P is any point on the level ground other than A the portion CB substends an angle beta at P. If AP:AB=2:1, then beta =

If C is the middle point of AB and P is any point outside AB, then

If C is the middle point of AB and P is any point outside AB, then

If C is the middle point of AB and P is any point outside AB, then

If C is the middle point of AB and P is any point outside AB, then

AB is vertical tower. The point A is on the ground and C is the middle point of AB. The part CB subtend an angle alpha at a point P on the ground. If AP = nAB , then tan alpha =
