Q. A person is 40 meters away from a building and sees the top of the building at an angle of elevation of 30 degrees. What is the height of the building?
A.
20√3 meters
B.
30 meters
C.
40 meters
D.
10√3 meters
Solution
Using tan(30°) = height / distance, we have height = distance * tan(30°) = 40 * (1/√3) = 40/√3 = 20√3 meters.
Q. A person is standing 20 meters away from a flagpole. If the angle of elevation to the top of the flagpole is 30 degrees, what is the height of the flagpole?
Q. A person is standing 25 meters away from a building and measures the angle of elevation to the top of the building as 36.87 degrees. What is the height of the building?
A.
15 meters
B.
20 meters
C.
10 meters
D.
25 meters
Solution
Let h be the height of the building. tan(36.87°) = h/25. Therefore, h = 25 * tan(36.87°) = 25 * 0.75 = 18.75 meters.
Q. A person is standing 25 meters away from a building and sees the top of the building at an angle of elevation of 30 degrees. What is the height of the building?
Q. A person is standing 25 meters away from a building and sees the top of the building at an angle of elevation of 60 degrees. What is the height of the building?
A.
25√3 meters
B.
15 meters
C.
20 meters
D.
30 meters
Solution
Using tan(60°) = height / distance, we have height = distance * tan(60°) = 25 * √3 = 25√3 meters.
Q. A person is standing 25 meters away from a building. If the angle of elevation to the top of the building is 36.87 degrees, what is the height of the building?
Q. A person is standing 25 meters away from a cliff and sees the top of the cliff at an angle of elevation of 75 degrees. What is the height of the cliff?
Q. A person is standing 25 meters away from a cliff and sees the top of the cliff at an angle of elevation of 60 degrees. What is the height of the cliff?
Q. A person is standing 30 meters away from a flagpole. If the angle of elevation to the top of the flagpole is 30 degrees, what is the height of the flagpole?
Q. A person is standing 40 meters away from a building and sees the top of the building at an angle of elevation of 60 degrees. What is the height of the building?
Q. A person is standing 40 meters away from a building and sees the top of the building at an angle of elevation of 45 degrees. What is the height of the building?
Q. A person is standing 40 meters away from a statue and measures the angle of elevation to the top of the statue as 53.13 degrees. What is the height of the statue?
A.
30 meters
B.
20 meters
C.
25 meters
D.
15 meters
Solution
Let h be the height of the statue. tan(53.13°) = h/40. Therefore, h = 40 * tan(53.13°) = 40 * 1.6 = 64 meters.
Q. A person is standing 40 meters away from a tower and sees the top of the tower at an angle of elevation of 60 degrees. What is the height of the tower?
Q. A person standing 30 meters away from a building observes the angle of elevation to the top of the building as 60 degrees. What is the height of the building?
Q. A person standing 30 meters away from a building observes the top of the building at an angle of elevation of 60 degrees. What is the height of the building?
A.
15√3 meters
B.
30 meters
C.
20 meters
D.
10√3 meters
Solution
Using tan(60°) = height / distance, we have height = distance * tan(60°) = 30 * √3 = 15√3 meters.
