A kite is flying 115 ft above the
ground. The length of the string to
the kite is 150 ft measured from
the ground. Find the angle to the
nearest degree that the string
makes to the ground.
Suppose the angle of elevation
from a ship to the top of a
lighthouse on top of a cliff is 6o.
The lighthouse is 60 ft tall and the
cliff is 250 ft high. Find the distance
from the ship to the base of the
ship.
The angle of depression from a hot
air balloon to its landing target is
12o. If the balloon is 175 ft high,
find its distance measured along
the ground from the target.
The angle of depression from an
airplane flying at an altitude of
5000 ft to the closer end of the
runway is 9o. Find the horizontal
distance from the airplane to the
runway.
