According to trigonometry, the distance from the camera to a particular unit in the parade can be represented by the formula d = a sec x, where a is the distance of the camera from the street and x is the angle between the street and the line of sight of the camera to the unit. Therefore, in this case, d = 26 sec x is the best choice.
