A vertical tower PQ subtends the same anlgle of `30^@` at each of two points A and B ,60 m apart on the ground .If AB subtends an angle of `120^@` at p the foot of the tower ,then find the height of the tower .

A vertical tower PQ subtends th same angle 30^(@) at each of two place A and B, 60 m apart on the ground, AB subtends an angle 120^(@) at the foot of the tower. If h is the height of the tower, then 9h^(2)+h+1 is equal to
