Two poles AB and PQ of the same height 35 m are standing opposite each other on either side of
the road. The angles of elevation of the top of the poles, from a point C between them on the
road, are 600
and 300
respectively. Find the distance between the poles.
First find the distance between BC using sin formula. Similarly find the distance between QC with sin formula. Therefore BC+QC=BQ which is the distance between the poles.
