A plane is located at C on the diagram. There are two towers located at A and B. The distance between the towers is 7,600 feet,
and the angles of elevation are given. a. Find BC, the distance from Tower 2 to the plane, to the nearest foot. b. Find CD, the height of the plane from the ground, to the nearest foot. Please show work! It is not multiple choice.

There are total 600 number of ways or permutations the top two finishers can be determined.
According to the given question.
Total number of people who are participating in a race = 25
In 25 participants the total number of participants to be selected to finish the race = 2
As we know that "a permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters". Which can be calculated as
Where,
is the number of permutations
n is the total number of objects
r is the numbers of objects to be selected
Thereofore,
The total number of ways, or permutaions the two top finishers can be determined is given by
= 25!/(25-2)!
= 25!/23!
= 25 × 24 × 23!/23!
= 25 × 24
= 600
Hence, there are total 600 ways or number of permutations the top two finishers can be determined.
