Two poles of height a and b stand at the centers of two circular plots which touch each other externally at a point and the two poles subtend angles of 30° and 60° respectively at this point, then distance between the centers of these plots is

Two poles of height 10 meters and 20 meters stand at the centres of two circular plots which touch each other externally at a point and the two poles subtend angles 30^(@) and 60^(@) respectively at this point, then the distance between the centres of these circular plots is

Two poles of height 10 meters and 20 meters stand at the centres of two circular plots which touch each other externally at a point and the two poles subtend angles 30^(@) and 60^(@) respectively at this point, then the distance between the centres of these circular plots is

Two circles touch each other externally at a point P and a direct common tangent touches the circles at the points Q and R respectively. Then angle QPR is

If two circles touch each other externally then the point of contact will on the line- segment joining the two centers___prove it.

Two poles of equal heights are standing opposite each other on either side of the road,which is 80m wide.From a point between them on the road,the angles of elevation of the top of the poles are 60^@ and 30^@ respectively.Find the height of the poles and the distances of the point from the poles.

Two poles of equal heights are standing opposite to each other on either side of the road which is 80m wide.From a point between them on the road the angles of elevation of the top of the poles are 60o and 30o respectively. Find the height of the poles and the distances of the point from the poles.
