4. Three people are watching a hot air balloon travel over their town. At a certain point in time, one person stands directly below the balloon, and the others look at it at certain angles. In the following image, A, B, and C are people, and D is the balloon. Person C is 384m directly below the balloon, Person B is 200m away from Person C, and the angle between Person A, the balloon, and Person B is 33o . How far is Person A from the hot air balloon

A stunt pilot is attempting to drop a water balloon from a
moving airplane onto a target on the ground. The plane moves at a
speed of 79.4 m/s and a 47° above the horizontal when the balloon
is released. At the point of release, the plane is at an altitude
of 560 m. Air Resistance is negligible Answer all parts to 3
significant figures.

Copy this diagram
and extend the pole length to create a transversal to the parallel
sun rays.
Your explanation in completing the problem should include full
sentences, using words. It should also make sure to refer to any of
the following three key facts you use to determine the angle with
vertex C:
(a) The vertical angles formed by intersection of two lines
are equal.
(b) The Parallel Postulate: If parallel lines are cut by
another line, the corresponding angles...

Consider a small town that has a population of 1,000 people. It is known that in this town, 10 people are infected with a rare disease. The remaining 990 people are NOT infected with the disease. This data is known with certainty. Recently, The FDA (Food and Drug administration) developed a test that determines if a person is infected with this disease. However, as with most test of this nature, it is not foolproof proof as there are a certain...
