Question

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 33∘33∘. From a point that is 250 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 49∘49∘. If we assume that the street is level, use this information to estimate the height of the building.

What is the height of the building in feet?

Thank you.

The angle of elevation from a certain point on the ground to the
top of a tower is 38∘. From a point that is 10 feet closer to the
tower, the angle of elevation is 41∘. Find the height of the tower.

The
angle of elevation from the top of an office building in New York
City to the top of the world trade center is 68°, while the angle
of depression from the top of the office building to the bottom is
63°. The office building is 290 feet from the World Trade Center.
Find the height of the World Trade Center.

From a window 55ft above the street, the angle of elevation to
top of the building across the street is 370 and the
angle of depression to the base of this building is 11o.

A surveyor stand 27 feet from the base of a building, measure
the angle of elevation to the top of the building and it is 55
degree. How accurately you must measure the angle so that the
percentage of error in estimating the height of the building is
less than 2%?

Two buildings are 40m apart. From the top of one
building, the angle of elevation to the top of the second building
is 10° and the angle of depression to the bottom of the second
building is 65°. How tall is each building?

A
surveyor is standing 30 feet from the base of a building, measures
the angle of elevation to the top of the building, and is at 55
degrees. How accurately should the angle be measured so that the
percentage of error in estimating the height of the building is
less than 2%?

The
angle of depression from the top of a building to a fountain is
38°. The fountain is 47 feet from the base of the building. Find
the height of the building.

1. Two identical eggs were thrown at the same time from the top
of a building of height 100 m at a speed 20. One egg was thrown at
an angle 40° above the horizontal while another was thrown at the
same angle but below the horizontal. How long does it take for the
other egg to hit the ground after the one of the eggs hits the
ground?
Does the time difference between the eggs hitting the ground

A coin is dropped from the top of a building. Its height s (in
feet) at time t (in seconds) is given by ?(?)= −16?^2 + 195
Find the average velocity of the coin over the interval
[1,2]
Compute the instantaneous velocity of the coin when ?=1
Compute the instantaneous velocity of the coin when ?=2
At what time will the coin hit the ground?
What is the velocity of the coin when it hits the ground?

A stone thrown from the top of the building is given an initial
velocity of 8 m/s at an angle of 20.0o below horizontal. It strikes
the ground 3.00 s later. (a) How far horizontally from the base of
the building does the stone strike the ground? (b) Find the height
from which the stone is thrown? (c) How long does it take the ball
to reach a point 10.0 m below the level of launching? (d) What are
