In the context of trigonometry, what is the line of sight?
AThe vertical distance from the observer to the object
BThe line drawn from the eye of an observer to the point in the object viewed
CThe horizontal distance between the observer and the object
DThe angle made by the object with the ground
Answer & Solution
Correct answer: B. The line drawn from the eye of an observer to the point in the object viewed
The line of sight is the imaginary straight line joining the observer’s eye to the point being viewed on the object. It is not itself an angle or a distance measured only horizontally or vertically.
