From her eye, which stands 1.63 meters above the ground, Samantha measures the
angle of elevation to the top of a prominent skyscraper to be 18°. If she is standing at
a horizontal distance of 201 meters from the base of the skyscraper, what is the height
of the skyscraper? Round your answer to the nearest tenth of a meter if necessary.


Sagot :

Answer:66.9 meters

Step-by-step explanation:

tan 18/1=x/201\

20tan18=x

201 tan 18=x

x=65.308858...

65.308858...+1.63=   66.938858...

≈  66.9 meters tall

The height of the skyscrapers is 66.9 meters.

Given

From her eye, which stands 1.63 meters above the ground, Samantha measures the angle of elevation to the top of a prominent skyscraper to be 18°.

If she is standing at a horizontal distance of 201 meters from the base of the skyscraper,

The angle of elevation;

The angle of elevation of the sun is the angle formed between the horizontal line and your line of sight when you look at the sun.

Then,

The height of the skyscrapers is given by;

[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}[/tex]

Substitute the values in the formula

[tex]\rm Tan\theta=\dfrac{Opposite \ side}{Adjacent \ side}\\\\\rm Tan18=\dfrac{x}{201}\\\\x = tan18\times 201\\\\x=65.30[/tex]

Therefore,

The height of the skyscraper is;

= 65.30 + 1.63 =  66.9

Hence, the height of the skyscrapers is 66.9 meters.
