and a sunken galleon.
B
The angle of depression from the salvage ship to the sunken
galleon is angle

C
The angle of elevation from the sunken galleon to the

D
Salvage ship is angle
in the picture.
Now consider the following: the salvage ship has located the sunken Spanish galleon at a slant distance of 1400
meters away, with an angle of depression of 30°.
a. How far must the salvage ship sail to be directly above the galleon?
b. How deep is the water at the galleon's location?
For both parts, first give the exact answer (simplify if needed) and then an approximate answer, rounded to two
decimal places, if appropriate.
a. Exact:

2. From a point on the floor, the angle of elevation to the top of a door is 47°, while the angle of elevation
to the ceiling above the door is 59°. If the ceiling is 9.8 feet above the floor, what is the vertical
dimension of the door? Round to 2 decimal places.

4. A 30-meter line is used to tether a helium-filled balloon. Because of a breeze, the angle of elevation of
the line is 85°.
a.
What is the height of the balloon (to 2 decimal places)?
b. If the wind becomes stronger, the angle of elevation will decrease. Write a function that gives
you the height h of the balloon depending on the angle 0.
