• A camper is hiking and is standing on top of a
  400 foot cliff enjoying the view. He looks down
  and views a bear at a 37o angle of depression.
  How far is the bear from the base of the cliff?
  (Round your answer to the nearest foot, and
  disregard the height of the camper in your
  calculations.)

1. Brians kite is flying above a field at the
end of 65 m of string. If the angle of elevation
to the kite measures 70?, how high is the kite
above Brians head?

2. From an airplane at an altitude of 1200 m,
the angle of depression to a rock on the ground
measures 28?. Find the distance from the plane to
the rock.

3. From a point on the ground 12 ft from the
base of a flagpole, the angle of elevation of the
top of the pole measures 53?. How tall is the
flagpole?

4. From a plane flying due east at 265 m above
sea level, the angles of depression of two ships
sailing due east measure 35? and 25 ?. How far
apart are the ships?

5. Tom and Sam are on the opposite sides of a
tower of 160 meters height. They measure the
angle of elevation of the top of the tower
as 40 and 55 respectively. Find the distance
between Tom and Sam.

6. A man on the deck of a ship is 13 ft above
water level. He observes that the angle of
elevation of the top of a cliff is 40 and the
angle of depression of the base is20. Find the
distance of the cliff from the ship and the
height of the cliff if the base of the cliff is
at sea level.

7. The angle of elevation of the top of a cliff
from the point Q on the ground is 30. On moving
a distance of 20 m towards the foot of the cliff
the angle of elevation increases to xo. If the
height of the cliff is 17.3 m, then find xo.

8. A communications tower is built on top of a
building with the following specifications from
a point 200 meters from the base of the building,
the angle of elevation to the top of the building
is 23.6 and the angle of elevation to the top of
the tower is 15.9. Find the height of the tower.

9. A ranger's tower is located 50m from a tall
tree. The angle of elevation to the top of the
tree is 10from the top of the tower, and the
angle of depression to the base of the tree is
20. How tall is the tree?
15
10. From the foot of a building I have to look
upwards at an angle of 22 to sight the top of a
tree. From the top of a building, 150 meters
above ground level, I have to look down at an
angle of depression of 50 to look at the top of
the tree.   a. How tall is the tree? b. How
far from the building is the tree?
