The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The distance from point C to point D is 258.8 meters.
<h3>What is Tangent (Tanθ)?</h3>
The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,

where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
The distance from point C to D is equal to the distance from point A to B. Therefore, the height of the building can be written as,
Tan(25°) = AB / BC
Tan(25°) × 555 m = AB
AB = 258.8 meters
Hence, the distance from point C to point D is 258.8 meters.

The equation in spherical coordinates will be a constant, as we are describing a spherical shell.
r(φ, θ) = 8 units.
<h3>
How to rewrite the equation in spherical coordinates?</h3>
The equation:
x^2 + y^2 + z^2 = R^2
Defines a sphere of radius R.
Then the equation:
x^2 + y^2 + z^2 = 64
Defines a sphere of radius √64 = 8.
Then we will have that the radius is a constant for any given angle, then we can write r, the radius, as a constant function of θ and φ, the equation will be:
r(φ, θ) = 8 units.

Answer:
50
Step-by-step explanation:
Let the event of people who believe that fuchsia is pink = A
Let the event of people who believe that fuchsia is purply = B
- Since 100 people were surveyed, the Universal Set =100
- 60 believe that fuchsia is ``kinda pink'', n(A)=60
- 27 believe it is both ``kinda pink,'' and also ``purply.'':

- 17 think that fuchsia is neither ``kinda pink'' nor ``purply.

We want to determine the number of those who believe that fuchsia is ``purply'', n(B).
In set theory, we have:

Therefore, the number of those who believe that fuchsia is ``purply'' is 50.
