Angle-of-Elevation Height: Calculate vertical height from horizontal distance and elevation angle in degrees.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Angle-of-Elevation Height to answer this question: calculate vertical height from horizontal distance and elevation angle in degrees? Enter horizontal distance and elevation angle in degrees; the calculator shows vertical height. For example: horizontal distance=35 and elevation angle in degrees=28 produce vertical height=18.60983010815176. The answer tells you vertical height.
Age 15Explain it to a 15-year-oldConnect it to the formula
For a level horizontal baseline, tangent converts an elevation angle and horizontal distance into vertical height. This page evaluates the relationship directly. The rule is c=a tan(b). Its input values are horizontal distance, elevation angle in degrees, and the main result is vertical height. For example: horizontal distance=35 and elevation angle in degrees=28 produce vertical height=18.60983010815176.
CollegeExplain it at college levelState the model precisely
This calculator evaluates the stated angle-of-elevation height relation over the valid real-number domain stated below. The implemented relation is c=a tan(b), evaluated from horizontal distance, elevation angle in degrees to produce vertical height. For a level horizontal baseline, tangent converts an elevation angle and horizontal distance into vertical height. This page evaluates the relationship directly. Instrument height and uneven ground must be accounted for separately in surveying applications.
Inputs and valid domain
- horizontal distance must be a finite real number.
- elevation angle in degrees must be a finite real number.
Important boundary: Instrument height and uneven ground must be accounted for separately in surveying applications.
The formula
c=a tan(b)
How the calculator works through it
It substitutes horizontal distance, elevation angle in degrees into the formula and exposes every numerical step above. The main output is vertical height.
Read the result correctly
The vertical height is the direct answer to “calculate vertical height from horizontal distance and elevation angle in degrees.” Read it with the units shown beside the inputs; a sign, angle, percentage or rate changes what the number means.
A worked check
horizontal distance=35 and elevation angle in degrees=28 produce vertical height=18.60983010815176.
Where this model stops being reliable
Instrument height and uneven ground must be accounted for separately in surveying applications.
Learn it by changing one value
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
