Gail wants to measure the distance AB across a small lake ( see the figure below ) . She walks 240 m away in a direction perpendicular to the line AB to a point C from which she can sight the point B. She then walks back 80 m along CA to a point P and then walks in a direction perpendicular to CA to a point in line with B and C. She finds that With this data, what does Gail find for PQ = 60m the distance AB ?
