A new building is being constructed a distance of 420 feet from the ocean, and the builder wants to have a rooftop patio

with a view of the ocean. Another building, in between the new building and the ocean, is located a distance of 180 feet

from the ocean and has a height of 15 feet. The angle of elevation from the ocean to the top of the new building, O.

represents the minimum angle for a person on the rooftop to view the edge of the ocean

Answer:

[tex]\theta = 4.8^\circ[/tex]

It is possible

Step-by-step explanation:

Given

See attachment for the construction

Solving (a): The minimum angle

This is calculated as thus:

[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

[tex]tan(\theta) = \frac{15}{180}[/tex]

[tex]tan(\theta) = 0.0833[/tex]

Calculate [tex]\theta[/tex]

[tex]\theta = tan^{-1}(0.0833)[/tex]

[tex]\theta = 4.761[/tex]

[tex]\theta = 4.8^\circ[/tex] --- approximated

Solving (b):

First; calculate the height of the building using the following equivalent ratio.

[tex]h : 420 = 15 : 180[/tex]

Where h is the height of the building

[tex]\frac{h }{ 420 }= \frac{15 }{ 180}[/tex]

[tex]h= \frac{15 }{ 180}*420[/tex]

[tex]h= \frac{15*420 }{ 180}[/tex]

[tex]h= \frac{6300}{ 180}[/tex]

[tex]h= 35[/tex]

This means that it is possible that the builder builds a 32 feet high building

From the picture attached,

Angle of depression = Angle of elevation (θ)    [Alternate angles]

Apply tangent rule in ΔCDP,

[tex]\text{tan}\theta=\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

[tex]\text{tan}\theta=\frac{CD}{DP}[/tex]

       [tex]=\frac{15}{180}[/tex]

       [tex]=\frac{1}{12}[/tex]

[tex]\theta=\text{tan}^{-1}(0.08333)[/tex]

[tex]\theta=4.76^\circ[/tex]

Use this property to get the height of the new building.

Since, ΔABP and ΔCDP are the similar triangles, their corresponding sides will be proportional.

[tex]\frac{AB}{BP}=\frac{CD}{DP}[/tex]

[tex]\frac{AB}{420}=\frac{15}{180}[/tex]

AB = [tex]\frac{420\times 15}{180}[/tex]

     = 35 feet

But the construction for a new building has a maximum height restriction of 32 feet.

And the height of the building is more than the restricted height.

    Therefore, it is not possible for the builder to have a rooftop patio with a view of the ocean.
