Question

A man wishes to estimate the distance of s nearby tower from him. He stands at a point A in front of the tower C and spots a very distant object O in line with AC. He than walks perpendicular to AC up to B, a distance of 100m, and looks at O and C again. Since O is very distant, the direction BO is practically the same as AO; but he finds the line of sight of C shifted from original line of sight by an angle 'a' = 40 degree. Estimate the distance of the tower C from his original position A.....
