Expert Solution & Answer
Answer to Problem 12CT
Solution:
The angle of depression from a hot-air balloon to the airport is 1.300
Explanation of Solution
Given information:
Height of the balloon is 600 feet and distance between Marshall Space Flight Center and airport is 5 miles.
As 1mile=5280feet
⇒5miles=5⋅5280=26400feet
That is, the balloon is flying 600 feet directly above the Marshall Space Flight Center and the distance between this flight center and airport is 26400 feet.
This can be represented diagrammatically as follows,
If two lines are parallel, then alternate interior angles are congruent.
Thus, from the figure ∠DAC≅∠ACB
Therefore,
⇒tanθ=144
⇒θ=tan−1(144)
⇒θ=1.300
Thus, the angle of depression from a hot-air balloon to the airport is 1.300
