Angle measurement of the height of a sign

This illustration demonstrates angle measurements used to calculate the height of a sign mounted on a building. The setup shows two lines of sight from a point on the ground, labeled as Point A, directed towards the base and the top of the sign labeled “NCG&E” at the top of the building. The horizontal ground distance from the observer’s position A to the building is marked as 205 feet.

These elevation angles are critical for applying trigonometric principles, such as the tangent function, to determine the height of the sign or the height difference between the base and top. This type of measurement setup is often used in surveying, construction projects, and architectural studies to determine vertical distances indirectly without requiring physical measurement up the side of a building.

This illustration is ideal for textbooks, math articles, or engineering publications.
