What is the height of a building if the angle of elevation to the top from a point on the ground is 31.4 degrees and from 53 feet further back it is 26.4 degrees?

It can be shown that:
- height = (d tan α tan β)/(tan α - tan β)
- α is the angle closest to the object
- β is the angle further away from the object
- d is the distance from the point of angle α to the point of angle β
height = (53 ft × tan 31.4° × tan 26.4°)/(tan 31.4° - tan 26.4°) ≈ 140.87 ft

The angle of elevation to the top of a building from a position on the ground 100 meters from the base of the building is 40 degrees how tall is the building?
tan40=x/100 100tan(40)=83.9m
What is the angle of elevation from the top of a bluilding from a point 165 feet away from the building on ground level is 26 degrees what is the height of the building?
The question is not quite clear but if the angle of elevation is 26 degrees at a distance of 165 feet away from the building then its height is 80.47587711 feet. 165*tan(26) = 80.47587711 feet
An engineer on the ground is looking at the top of a building the angle of elevation to the top of the building is 22 degrees the engineer knows the building is 450 ft tall what is the distance?
If the engineer's eye is at ground level, then the distance to the point on the building underneath its highest point is 450/tan(22) ft. If the engineer was standing and his eyes were x ft above the ground, the distance is (450-x)/tan(22) ft.
A building is 60ft high From a distance at A on the ground the angle of elevation to the top of the building is 40 From a lil nearer at B the angle of elevation is 70 Find the distance from A to B?
Using the formula: tangent = opposite/adjacent whereas tangent angle = height/ground distance, will help to solve the problem
What is the Angle of elevation of Qutub Minar when you are at a distance of 5metre using trigonometry?
If you are looking for the angle of elevation from the ground to the top of Qutub Minar, here is a solution. Qutub Minar is 72.5 meters tall. The angle of elevation would equal arctan(72.5/5). It comes out to approximately 86.05 degrees.
