A man wishes to estimate the distance of a 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 then walks perpendicualr to AC upto B, a distaance of 100m and looks at O and C again. Since O is very distant, the direction of BO is practically the same as AO, but he finds the line of sight of C shifted from the original line of sight by an angle `theta = 40^@ ( theta "is known as parallax").` Estimate the distance fo the tower C from his original position A.

To estimate the distance of the tower C from the man's original position A, we can use the concept of parallax and trigonometry. Here’s a step-by-step solution: ### Step 1: Understand the Setup - The man is standing at point A in front of the tower C. - He walks perpendicular to the line AC to point B, a distance of 100 m. - The angle of parallax (θ) is given as 40°. ### Step 2: Identify the Triangle ...
