Angle of Elevation An engineer erects a 75-foot cellular telephone tower. Find the angle of elevation to the top of the tower at a point on level ground 50 feet from its base.
Consider a cellular telephone tower, ABhigh and a point
on the level ground at a distance of
from its base
Since the tangent of the angle is given by the ratio of the length of the perpendicular to the base
Put the values
Hence, the angle of the elevation to the top of the tower at a point 50 feet from the base of the tower is

The angle of elevation to the top of a tower from point A on the ground is 19.5 degrees .19.5°. From a point B,38.5 feet closer to the tower, the angle of elevation is 21.7°. What is the height of the tower in feet?
From the top of tower A the angle of elevation of the top of tower B is 46 degrees, from the foot of tower B the angle of elevation of the top of tower A is 28 degrees. Both towers are on level ground. If the height of tower B is 120 m, how high is tower A?
14. A wire holding a tower makes a 73° angle with level ground. At a point 30 feet farther from the tower than the base of wire (but on the same side as the base of the wire), the angle of elevation to the top of the tower is 35º, (see Figure (2) in the attachment Final Exam Figures.pdf). (a) Determine the unknown agles of triangle ABC. (b) Use the law of sines (apply it to triangle ABC) to calculate...

To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 39 degrees From a point that is 350 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 53 degrees. If we assume that the street is level, use this information to estimate the height of the building.
1. The angle of elevation to the top of a very tall Building is found to be 8° from the ground at a distance of 1 mi from the base of the building. Using this information, find the height of the building. (Round your answer to the nearest foot.) _______ft 2. A 19-ft ladder leans against a building so that the angle between the ground and the ladder is 71°. How high does the ladder reach on the building? (Round...
One hundred feet from the trunk of a tree on level ground, the angle of elevation of the top of the tree is 370. Estimate the height of the tree to the nearest foot.
The angle of elevation to the top of a Building in New York is found to be 5 degrees from the ground at a distance of 1 mile from the base of the building. Using this information, find the height of the building. Round to the tenths. Hint: 1 mile = 5280 feet Your answer is feet. The proper angle for a ladder is about 75 degrees from the ground. Suppose you have a 4 foot ladder. How far from...
An electrical tower of height 12 feet stands 21 feet away from a 20-foot tall building. A support cable stretched from the top of the tower to a point on the ground and then back to the top of the building. How far from the base of the tower should the cable be attached on the ground so that the least amount of total cables is used? You must set up an appropriate function to get credit. Show all work....
